2-1/8" button in dark blue on a gray bkg. Curious word play combining Republican-Elvis-Pelvis. Reverse is a covered metal back with horizontal bar pin. Side edge curl has small 1/16" cello nick but o/w the piece is undamaged. No maker's name or text other than the slogan on the front. Manufacturing style would be consistent with 1956 era. Only one we've seen but we had exact item in Auction 195 where it exceeded $200.00.
