Display board system

1. A mounting structure comprising:

at least one display board including a first mounting interface and a second mounting interface;

a first pivotal interface including a first projection forming a retaining slot adapted to engage the first mounting interface of the display board wherein the first projection is a hook; and

a second pivotal interface adapted to engage the second mounting interface of the display board;

so that the display board is adapted to be removably pivotally coupled to the mounting structure at both the first pivotal interface and the second pivotal interface.

2. The mounting structure of claim 1 wherein the second pivotal interface includes a second projection having a post.

3. The mounting structure of claim 1 wherein the second pivotal interface is adapted to be generally coaxial with the second mounting interface.

4. The mounting structure of claim 1 wherein the first pivotal interface is configured to at least partially grip the first mounting interface of the display board.

5. The mounting structure of claim 1 further comprising a cap having the first pivotal interface and a base having the second pivotal interface.

6. The mounting structure of claim 5 further comprising a frame coupling the cap to the base.

7. The mounting structure of claim 6 wherein the frame is adapted for mounting to an existing structure.

8. The mounting structure of claim 6 further comprising a cover fitted over the frame.

9. The mounting structure of claim 5 wherein the cap includes a plurality of first pivotal interfaces and the base includes a second pivotal interface for each of the first pivotal interfaces so that the mounting structure is adapted to receive and support a plurality of display boards.

10. The mounting structure of claim 1 wherein the first and second pivotal interfaces are generally coaxial.

11. The mounting structure of claim 1 wherein the second pivotal interface is disposed below the first pivotal interface.

12. A mounting structure comprising:

at least one display board including a first mounting interface and a second mounting interface;
