Original 1st printing 17&7/8 x 23&5/8" concert poster for the one and only Ten Years After (featuring Alvin Lee) appearing with Buddy Miles and Brethren at Madison Square Garden in NYC on 11/13/1970.
Designer unknown/uncredited, medium-thin glossy textured stock poster is in used (C) condition; a pair of horizontal/vertical folds, heavy edge/corner wear (numerous tears, areas of missing paper, pulls, etc...), numerous surface marks and heavy creases/folds... this example was quite obviously pulled down from public display in 1970. Still, a VERY uncommon/scarce early MSG concert poster for the UK blues-rock titans.
Interestingly enough, this show was presented by Howard Stein's Capitol Theatre organization (in conjunction with Chrysalis Records). Cool piece.
