I can just see Chuck Berry with his 355 in that color guitar & year with his giant Bellbottoms doin his famous duck walk!!Real Beauty. A friend bought the almost exact guitar brand new in 1974. Same color except that his had metal bridge pieces for each string. So I'd say 69 - 73 or so. Played that guitar often and realized that Gibson was still making really great ES-335's right through the early 70's. Gibson got heavily into finishing Gibson ES -335's and SG's that color and that color was very popular at the time and I still really that color. It takes you back.
