2-3/16” scarce button reading in full “From ‘Hoss’ Cartwright/To A Bonanza Sirloin Pit Buddy.” From the earliest days of the franchise restaurant chain and only the second example we’ve seen. Center has 2 tiny raised bumps caused by the reverse bar pin. There is also a little scattered browning on the white bkg., most noticeable as a few tiny tan age dots around the upper rim. Still has full color and high gloss. Fine.
