The first series cards (#1 - 36) in the 1949 BOWMAN set with 3rd series (cards #4, 74 - 108) overprints are not that rare.
The HIGH # cards with overprints are very rare. Here are some of my Hi # overprints. Cards in the series numbering #145
to 180 overprinted with cards #217 - 240 and the 12 variations.
