11. The knockdown assembly according to claim 1 wherein each upper blank sidewall segment defines a display opening cutout.

12. A display tray formed from the knockdown assembly according to claim 1 .

13. A knockdown assembly configured to be assembled into a display tray having first, second, third and fourth side panels and four corner columns, the knockdown assembly comprising:

a lower blank comprising a lower blank central region having first, second, third, and fourth edges and surrounded at each edge by first, second, third and fourth sidewall segments, at least the first and third sidewall segments including a rollover portion, wherein each of said second and fourth sidewall segments extend from a respective first end to a respective second end, and wherein end flaps are attached to each first end and each second end of both the second and fourth sidewall segments;

an upper blank comprising an upper blank central region having first, second, third, and fourth edges, a first sidewall segment attached at the second edge, a second sidewall segment attached at the fourth edge, and first, second, third, and fourth column portions extending from first, second, third, and fourth corners of the upper blank central region,

said upper blank central region and said lower blank central region having substantially the same shape and are substantially equal in size;

wherein a lower surface of the upper blank is adhesively attached to an upper surface of the lower blank so as to line up the upper central region on top of the lower central region.

14. The knockdown assembly according to claim 13 wherein each column portion includes a median edge integral with the upper blank central region and a lateral edge, wherein each column portion is folded upon itself, and wherein the lateral edge is secured proximate to the median edge.

15. The knockdown assembly according to claim 13 wherein each column portion includes a plurality of fold lines dividing each of said column portions into at least three column walls, wherein one of said column walls of each of said column portions is adjacent to and in face to face relationship with one of said second and fourth sidewall segments of said lower blank.

16. The knockdown assembly according to claim 15 wherein said column walls are foldable relative to one another about said fold lines such that each of said column columns has a polygonal cross-section when said knockdown assembly is assembled into said display tray.
