I lived in Seattle for 20 years and ate at Shakey's many times as a youngster. This set stirred memories of overheated pepperoni and steak fries, two staple ingredients from their all-you-can-eat pizza bar. *BURP*
This card back packed in a lot of info and still left space for a corporate logo. Note Wagner's spirited nickname, "The Flying Dutchman," a moniker that plays off the ghost ship (a legend better-known in his time) to salute his base-running skills.
According to Baseball-Reference.com, Honus's career stats differ from this 1976 version in every listed category. He somehow "lost" 10 hits, perhaps from better research into Wagner's 19th-century career with the Louisville Colonels. At least they got those cradle and grave dates right!
Value: Oddball set or not, Wagner commands higher prices than most old-school players. This card cost $8 on eBay, which feels a little high, but not unconscionable.
Fakes / reprints: I doubt that fakes of such a low-profile set would be worth printing.
