One of the reason that the Golden age books from the 30’s and 40’s are so rare as compared to Silver (60s-early 70s), etc is due to the paper drives during WWII. Huge amounts of comics, magazines, newspapers, etc were gathered for those drives and it was considered a civic duty to turn them in.
Most of the ones that remain were either found in serious collections from business men well past draft age when those owners passed or discovered in attics and other out of sight places.
Gosh, I hadn’t thought of paper drives in forever.
Now I’m worried that soon nobody will print newspapers anymore, and what will I line my bird cages with?
