1964 Challenge the Yankees #50 [Also 1965] Carl Yastrzemski [.294] (Red Sox

1957 was the beginning of the modern era of baseball cards and their to this day standard size of 2-1/2" x 3-1/2". Many collectors consider the 1957 set the most attractive of the 1950's sets. Of note is a fun error card picturing Hank Aaron batting left-handed. The error was never corrected so there is no extra value.

The set included some very neat multi-player cards and was PACKED with ROOKIES !!!
Frank & Brooks Robinson, Don Drysdale, Jim Bunning, Rocky Colavito, Kubek & Richardson

Man was the 1948-1949 Leaf baseball set PACKED !!! The set was small in numbers and size with only (98) 2-3/8" by 2-7/8" cards. With only 98 cards, the set was "skip-numbered" with card numbers from 1 thru 168. Likely an attempt to force collectors to keep buying packs looking for their missing cards. (49) cards are considered "Short Prints" and there is one variation card #136: Full Sleeve/Short Sleeve (error)
