I believe this series of advertising campaign photo proofs are probably a one of a kind item. These were taken by Don Berg's advertising photography studio in Minneapolis, it looks like in the 1960's. I don't know if this was ever used in any campaign, but they should have been, I think they are great.
The photos each have some (water?) damage on their tops; the third has a fold on the on sale lower right corner. They each are stamped on the rear lower right corner with the studio information with their individual negative number in pen. Each also is numbered 1, 2, or 3 in what appears to be colored pencil on the upper left rear corner.
These photos are 8 x 10. It's hard for me to express how much I love these. They epitomize everything important about early '60's advertising. This is so completely "MadMenesque" and mid-sixties super cool. I think you really want this.
