I'm drawn to Bob's 1971 Kellogg's 3-D, a superior card in every way. Ditto his 1967 Coca-Cola premium, as produced by, but by no means distributed by, the company chosen by the Coca-Cola company to print this piece--Dexter Press.
I only own the Kellogg's, but have cherished it since I pulled the card from a cereal box the summer of '71. That was a real prize!
