Auction says "Produced by the Sporting News in 1983 in conjunction with the publication of the classic stadium book, "Take Me Out to the Ballpark," this suitable-for-framing lithograph by notable cartoonist Amadee features great moments at Tiger Stadium and head shot illustrations of Hall-of-Famers Al Kaline and Ty Cobb."
