Frank Zappa/Mothers Of Invention: Mothermania. 1970s U.S. Color Laminated Pinback Button. 1 3/4 inch round laminated button cover of the Mothermania 1969 LP. This button is old with no wear on image and I have no clue where I got it! Or who issued it. It has been in my collection over 35 years. Zappa collectors also said it is an oddball FZ item. In plastic sleeve. Mint. Deleted WW.
