Is this the only card to feature two different players sliding? It might very well be. 25 steals is already impressive, but consider they came in a 5-game series. These days, teams are lucky to take 10 extra bases combined.
Baseball and cartoon artist Bob Laughlin first self-published a black-and-white World Series set in 1968. (This blog profiled its #5 in early 2009.) When Fleer contracted with him to republish a color version, they replaced active MLBPA union members--including 1967 series hero Bob Gibson--with non-player images.
There's a ton of great World Series set info out there, but these 2 articles also talk about Laughlin's influence on collecting, publishing, and cards in general.
- Look back at 1st issue of Laughlin's Inside Pitch newsletter (The Fleer Sticker Project)
- "Fleer World Series Cards Worth a Laugh" (SCD in 2009)
Value: They run a couple dollars each, perhaps more for cards picturing legends like Babe Ruth.
Fakes / reprints: This is a fairly popular re-issue set, but I haven't seen any reprints in the market.
