Pre-WWII definition for card collecting

[drc]

It was a legitimate question. Consider "Pre War" as a standard general category, partly a product convenience, with the exact cut off dates being blurry and a matter of opinion. The hobby generally goes by 1941, but that date is mostly about the production of baseball cards as anything else. When the US entered the war in 1941, baseball card production almost ceased until after the war. 1941 is a clear cutoff date in baseball card history if not WWII. In 1946, US baseball card production started up again, starting the 'Post War' baseball card era. So the cutoff dates were mostly defined by the cards themselves rather any battle or declaration of war.
