I hope I don't get kicked out for showing up with nothing here anyone else would care about, but at least let me highlight a great ebay seller, goose_1, thru this show and tell.
All I bought was the 1974 Hank Aaron postcard in the upper left, just for a couple bucks. But when the enveloped arrived, I got the George Hendrick postcard, the Hartnett/Ruth photo, and the True Value Seaver/Yount panel. (Ignore the two old Isaac Newton cards purchased separately.)
I know the whole pile will strike many of you as throwaways, but I really enjoyed the surprise. (BTW, since I'm calling out a seller, my name is Jason Schwartz.)
