I am wondering if there are some books out there that I am missing in the
vintage baseball CARD arena. I am a type collector from 1900-1939 and am looking for works which would help elucidate this time period particularly.
I have Burdick's ACC, Lipset's 3 volumes, Heitman's The Monster, Mark Peavy's
T206, Canfield's tome on Tobacco Era Card Packs, Ron Erbe's American Premium Guide to Baseball Cards, Egan's Tobacco Cards, Zappala's The
206 Collection, Slocum's Classic Baseball Cards, Oser's Cardboard Gems,
Hornes' Zeenuts, Erik V.'s Philadelphia Caramels, Reader's e-books.

Any others that I'm missing which are illuminative of CARDS from the 1900-1939 era.
I know there are price guides and internet helps but I am really focusing here
on books such as the ones listed above.
Many thanks for any help.
all the best,
