Promotional Rock Band Buttons/Pinback set of 4 Duran Duran, INXS, I.R.S.

Description

These buttons are promotional items that were sent to radio stations from record companies in the 80's and possibly the 90's to promote their bands and new album releases.  Many of these buttons were never available on the open market.  They have never been worn only displayed.  Duran Duran, INXS, I.R.S. and one, with blue stripes, that I do not know.  Thank you for looking.
