Vintage 80s Sesame Street Live Bert & Ernie Button Lapel Pin Pinback Souvenir

This is an awesome Sesame Street Live pin / button / pin-back featuring Bert and Ernie. Its about 3.5" across- so a nice and big statement piece! This button is in very good vintage condition. The front shows no flaws. The back has some patina/ aging/ discoloration to it, but only can be seen from the back- see photos for details. A great vintage find!
