huge lot 300+ pin back buttons badges, 70s 80s vintage pinbacks w/ advertising etc.

Huge lot of vintage pin back buttons - I know very little about this type of thing or pop culture in general, so these are unpicked, all as found in one lot.

This is the collection of one lady from small town Wisconsin - I didn't see a lot of national interest pieces here, nearly no political buttons besides Geraldine! These are mostly 70s and 80s vintage, I think. Quite a few duplicates.
