First is a 3" litho tin button we've offered only once or twice before. It was issued to promote the pin-ball game with text reading "Gottlieb's Buck Rogers/Star Of The 80s." Curl carries 1979 copyrights of both Universal City Studios and Robert C. Dille. Pictured in illustration style are the stars of the TV series. Essentially Mint. Next is button we've never offered before. It is a 2.25" litho with metal back and bar pin. Pictured is the star of the 1980s TV show with complete text reading "Gil Gerard/'Buck Rogers In The 25th Century'/Read-A-Thon/Mystery Sleuth." About ten tiny paint rubs 1/16" or less along the left edge but rest is clean and glossy. Circa 1980 and rare.
