Likely issued between 1937 and 1938, the Big League Baseball Movies was a series of small (2" x 3") "Flip Books" whose pages were meant to be flipped quickly, producing a "movie."  The issue included 13 different players, each movie produced in two parts, for a total of 26 books.  This collection includes three "part one" books - #3 Mel Ott, #5 Wally Moses, and #10 Paul Waner.  All three books are intact and present in VG condition.  Also included is a small booklet issued by Sears Roebuck called "How to Pitch by Dazzy Vance," measuring 2 3/4" square, a 12-page booklet containing pitching tips from the Hall of Famer.  G-VG condition with some wear.  Four pieces total.
