Original 1st printing 13&3/4 x 28&5/8" concert poster for an all-blues show featuring John Mayall, Bo Diddley, Muddy Waters, Otis Spann and Magic Sam appearing together at Winterland in San Francisco, CA from 3/27-29/1969.

 

 Art by Greg Irons, image (handbill w/extra ticket strip) is featured in the Art of Rock on page 349 (plate 4.55).

 

  Medium-thick flat index stock poser is in good to very good (B to B/B+) condition; a series of semi-hard horizontal bends, a few tiny pulls and creases around the outer margins, a pair of small edge tears in the lower left margin and a couple of thin pinch/stress bends scattered here and there, otherwise fine.
