I hadn't been aware of the 144-card 1960 Leaf baseball set until just a month ago. The cards are, as I'm sure you can see, black and white, and each contains well-written biographies on the back along with 1959 and career stats. I happened to have liked what I saw online when I first encountered them, so put in a small bid for a lot of 3 on eBay, and....I won! I won!
Here's 3/144ths of that 1960 Leaf set!
