yeah. (snaps fingers).

I think this was originally purchased by my parents in the early-to-mid 70s as part of an "auction box"-- in this case, a round tin filled with buttons and whatnot that my sister and I loved to sort and sift through. The tin itself probably dated to the 20s, but the contents were from whenever. The pin must have been from the 30s to 40s. ???
