HUGE lot vintage enameled metal pins, WBA women's bowling regional club pins

HUGE lot of enameled metal pins (about 5 3/4 pounds!), most pins from WBA clubs and events from all over the country, though some of these are just travel souvenirs I think.

Some duplicates, these are all from a tremendously large collection from the 70s, 80s and 90s. I know nothing at all about bowling leagues, but these look cute and fun with some great graphics! Most are in excellent condition.
