Questions about 1960 Post Cereal "cards"

[AustinMike]

Here's a picture of my Mantle. I don't have a picture of the back but there are no glue stains. I know I also have a Drysdale here somewhere and possibly a Mathews, but they've apparently found a good hiding place. Once I locate them I'll send pictures of them.

In the meantime, here's a link to a Sotheby's auction from 2007.

A set of 9 complete boxes comprised the lot. Three of the boxes indicate they are "LARGE SIZE" and the other six have no such indication. The "LARGE SIZE" boxes definitely have more room on the back (more space between card and edges, larger font size for "SPORT STARS" etc.). Based on the photos, I'd guess that my Mantle came from a large size box.

Unfortunately, the fronts of the boxes aren't shown. When I got my Mantle, it came with a Grape Nut Flakes front of the box panel that allegedly was from 1960. But I think the front panel actually dates from 1961 based on the baseball card promo pictured on it. When I find the Drysdale and hopefully Mathews, I'll also send a picture of the front of the box that I have.
