Original 1st printing 13&3/4 x 22&1/8" concert poster for the Allman Brothers Band appearing with the Marshall Tucker Band at Winterland in San Francisco, CA on 9/26/1973.

 Art by (and SIGNED in black pen by) David Singer, image is featured in the Art of Rock book on page 319 (no plate #).

 Medium glossy-coated index stock poster is in good/decent (B to B/B-) condition; there is a fairly extensive degree of fading to the image area, with a bit of uneven discoloration/matte burn around the outer margin area and a light amount of handling wear, but that's pretty much it... physically, it's in great shape- just VERY faded.
