Winston SF
(A 2004 classic!)
The Illustrious Mr. Chung sent me this link to a site devoted to the wonderful YA series of SF novels published by the John C. Winston Company in the late 1950's and early 1960's. The artwork was wonderful, and many of the books are still fun to read today.
Triva time! The following Winston authors were really sombody else!
Evan Hunter...Ed McBain
Philip Latham...Robert Richardson (astronomer)
Milton Lesser...Stephen Marlowe
Eric North...Bernard Charles Cronin
Philip St. John...Lester Del Rey
Erik Van Lihn...Lester Del Rey
Kenneth Wright...Lester Del Rey
