Modern Tip Trays

Announcing the collaboration between J.L. Clark, a metal packaging company and Lippincott and Margulies, a brand and design company, these advertising tip trays are just iconic mid century modern graphic design examples. The colors and presentation are so delightful! I'm not sure when this collaboration took place, a quick search did not reveal. The trays are all the same and measure 7.25" x 5" in excellent condition.
