Below I've scanned a page from The Great American Baseball Card Flipping, Trading and Bubble Gum Book...a.k.a. The Card Collector's Bible. The books is notorious for not labeling the cards that are discussed and I am having trouble figuring out which set two of the cards listed are from.
I've circled them in green below and they seem to be from the same set and have some awesome die-cut corners. Can anyone give a little help?
