This is a nice example of an early 1970s Martin Style 28 Tiple with Indian rosewood back and sides (looking quite a bit like Brazilian) set off with The board and bridge and ebony. Very clean, no cracks, and with the signature of Chris Martin IV on the inside back center brace. Overall excellent condition and in the origiinal hard case. 17-1/16″ scale, 1-7/16″ nut.
