Most Sport Hobbyist cards depict players active before WWII, an era largely out-of-reach to modern set builders. The "Famous Cards" checklist goes a step further by replicating actual cards released many years earlier, including this 1916 Sporting News (a.k.a. M101-5) Jack Barry.
This Hobbyist type card shows Jack Barry's picture with no frame or text, possibly to avoid confusion with an authentic example from 1916. Most "Famous Cards" measure larger than the originals; compare this scan with Jack Barry as M101-5 #11.
Frank Nagy pulled double-duty on set backs by including both vintage set details and his Sport Hobbyist business address. He got card dimensions and set count right, but 1960s collectors probably didn't have a complete list of set variations; Old Cardboard's M101-4/5 checklist details those differences. (See also my profile of 1916 Sporting News #5, Leon Ames.)
Just for fun, I searched Google Maps for 12795 Wade St in Detroit, but didn't find anything more inspiring than a locksmith. Anyone out there know more about the Sport Hobbyist's fate?
Value: Vintage reprint sets vary in demand and price, but you might find singles for under $5 and the whole set for $100-150.
Fakes / reprints: It's already a low-value reprint, so I doubt anyone went to the further trouble of counterfeiting them.
