Gretsch Permatone Coated Bass Drumhead 20" w/Offset Logo

I have a 1962 Gretsch Round Badge six ply Progressive Jazz drumset with a 14 x 20 bass drum. when I acquired this set, the bass drum had a black reso head which has been in the drum for too many years. The head which I bought is the OEM rhapsody was on the drum when new and the same head is OEM for Gretsch USA Custom bass drums.
