It bugs me that Harrelson gets no Boston cap love on this card. He's the league's #3 slugger, spent all year with the Red Sox, and Topps couldn't be bothered to get something better that an airbrushed shot from his days with KC or Washington? THE HAWK DISAPPROVES.
I do like that they highlighted 1968's grand slams. Jim Northrup's 4 is quite an achievement in any year and Joe Foy hit 2 out of only 10 total homers! (Note that Mantle only hit 18 round-trippers in 1968, his final year, but still walked more than 100 times.)
Value: You can probably find this card for $1 in low-to-mid grade. Leader cards with Hall-of-Famers run up to $10.
Fakes / reprints: Haven't seen any reprints of this card specifically, though Topps used this set design for a bunch of vintage-style cards in the modern era.
