A beautiful  first printing of BG-29, the poster from the Bill Graham Series known as THE SOUND, with art by the great Wes Wilson.  This advertised 1966 shows at the Fillmore and Winterland by the Jefferson Airplane, Muddy Waters and the Butterfield Blues Band.

This is the first printing color version, designated OP-2 (it was also printed in black and white.) This example is in Near Mint/Excellent condition, with tiny pinholes at the top and bottom center, a small crease to the top left corner, and a small pinch-type crease to the bottom left corner.  There are a few small and faint splash spots on the back, along with a 25 cent price tag.  None of these detract significantly from the bold, unfaded beauty of this poster–it will frame beautifully.  A classic and sought after early Fillmore poster.  (Note- the colors of the photo here are a bit darker than in reality; the purple is the ligher variation as described in Eric King’s guide for OP-2).
