Pat R: “My friend's mother purchased a set for him and he told me that she purchased them from an ad in the NY Times. There are images of all of them in post #53 in the old thread.”

Pat: What we now know teaches that the images in post #53 of the old thread (cards of your friend) are from the Festburg cards discovered in NJ 1980s- Ivory / Beige paper stock, squared corners, 2 ¼ x 3 ½, .1mm thick, weight 1 gram. It could be the same set… from the letter from The Sporting News from the 1980s…from Stanley Apfelbaum see post 140 in this thread.
As for Matt74 his cards may not be from the Festburg discovered, he says his cards have cream colored backs that are almost white. I have reached out to him, maybe he can post images of his cards front and back. I am thinking they should look like the images below only with squared corners, 2 ¼ x 3 ½, .1mm thick, weight 1 gram.
PS> The first two cards show as cream white: The Festburg card is the one in the middle. Again remember we are not seeing the true colors of the cards.
Thanks John.
