Retro American Girl Grin Pin collection. Thr grin pin collection started in 1994 and was later discontinued in the 2ks. The banner, measures 19.5" x 31", is made of black duck cloth. There is space for 143 pins. most of them have been collected here. I am going to check for any stragglers I might have to round out the banners collection but this will greatly holster your own collection and hopefully even complete it!
