3. The architectural wall panel according to claim 1 , wherein at least a part of the second leg of the clip extends obliquely relative to the upper flange in the forward direction.

4. The architectural wall panel according to claim 1 , wherein the second leg of the clip extends beyond a perimeter of the face plate defined by the lower end.

5. The architectural wall panel according to claim 1 , wherein the first leg of the clip extends to a position on one side of a perimeter of the face plate defined by the lower end and the second leg of the clip extends to a position on an opposing side of the perimeter of the face plate defined by the lower end.

6. The architectural wall panel according to claim 1 , wherein the first projection of the upper flange is a double walled structure.

7. The architectural wall panel according to claim 1 , wherein the panel body is unitarily formed.

8. The architectural wall panel according to claim 1 , wherein the first and second effective widths are defined where the clip is engaged with the projection.

9. An architectural wall panel system comprising:

a plurality of unitary panel bodies including at least a first panel body and a second panel body;

the first panel body including a generally rectangular face plate having an upper end, a lower end, a forward facing front side and a rearward facing rear side, a lower flange generally extending rearward from the lower end and terminating in a clip;

the second panel body including a generally rectangular face plate having an upper end, a lower end, a forward facing front side and a rearward facing rear side, an upper flange generally extending rearward from the upper end and including a transversely extending first projection, the first projection having a forward facing front side extending parallel to and a rearward facing rear side and defining a second width therebetween;

the clip of the first panel body including a first leg extending toward the upper flange and a second leg extending away from the upper flange, the first leg of the clip of the first panel body extending in a first plane parallel to the front side and being configured to engage the front side of the first projection of the second panel body, the second leg of the clip of the first panel body being configured to engage the second side of the first projection of the second panel body, the first and second legs of the clip being spaced apart from one another and having a minimum gap defined between the first plane and the second leg as a first effective width, the second width being greater than the first effective width; and

whereby the first and second legs of the clip of the first panel body exert a pinching force on the first projection of the second panel body when said first projection is located between the first and second legs.

10. The architectural wall panel system according to claim 9 , wherein at least a part of the second leg of the clip extends obliquely relative to the upper flange.

11. The architectural wall panel system according to claim 9 , wherein at least a part of the second leg of the clip extends obliquely relative to the upper flange in the forward direction.

12. The architectural wall panel system according to claim 9 , wherein the second leg of the clip extends beyond a perimeter of the face plate defined by the lower end of the first panel body.

13. The architectural wall panel system according to claim 9 , wherein the first leg of the clip extends to a position on one side of a perimeter of the face plate defined by the lower end of the first panel body and the second leg of the clip extends to a position on an opposing side of the perimeter defined by the lower end of the first panel body.

14. The architectural wall panel system according to claim 9 , wherein the first projection of the upper flange is a double walled structure.

15. The architectural wall panel system according to claim 9 , wherein the plurality of panel bodies are identical to one another.

16. The architectural wall panel system according to claim 9 , wherein the first and second effective widths are defined where the clip is engaged with the projection.

17. An architectural wall panel system comprising:

a plurality of unitary panel bodies including at least a first panel body and a second panel body;

the first panel body including a generally rectangular face plate having an upper end, a lower end, a forward facing front side extending parallel to a rearward facing rear side, a lower flange generally extending rearward from the lower end and including a clip spaced apart from a terminal tail end of the lower flange, the clip including a first leg extending toward the upper flange in a first plane parallel to a second leg extending away from the upper flange;

the second panel body including a generally rectangular face plate having an upper end, a lower end, a forward facing front side and a rearward facing rear side, an upper flange generally extending rearward from the upper end and including a transversely extending first projection spaced apart from a terminal portion of the upper flange by a rearwardly extending intermediate portion, the first projection having a forward facing front side extending parallel to a rearward facing rear side and defining a second width therebetween;

the first leg of the clip of the first panel body engaging the front side of the first projection of the second panel body and forming a first seal, the second leg of the clip of the first panel body engaging the rear side of the first projection of the second panel body and forming a second seal, the terminal tail end of the lower flange engaging the intermediate portion and forming a third seal, the first and second legs of the clip being spaced apart from one another and having a minimum gap defined between the first plane and the second leg as a first effective width, the second width being greater than the first effective width; and
