National Visual Aids Baseball Posters
 

I picked up a lot of 11x14 cardboard posters with historic baseball players. The seller called these “1975 National Visual Aid Posters,” and said they were part of a series of 50 posters, and was aware of another set of of 50 more posters. They are numbered with “SP” either before or after the number. Several of these are also stamped with school or library markings, and some have text that was printed and affixed to the back (perhaps for a teacher to read to students?)

If anyone has more details about these, please share.

Showing some of the better pics from the lot.
