Set of three (3) original 1st printing 17&1/2 x 23&1/4" silkscreen concert posters for Mahavishnu Orchestra (featuring John McLaughlin) appearing with the Rowan Brothers at Irvine Auditorium on the campus of the University of Pennsylvania in Philadelphia, PA on 12/9/1972. 

 Art by (and SIGNED and numbered 5/16 (full color), 30/36 (blue/red only) and 1/10 (pink) in pencil by) by Thomas Bolles, medium-thick flat vellum stock hand-pulled silkscreen posters are all in excellent (B+) condition; a couple of them have a few light handling dings/corner-tip bumps and the full-color version has a pin-prick age spot or two, but overall the set is VERY sharp.

 Totally cool set of early-'70's Mahavishnu posters, these came right from the artist's personal archives.
