Original 1st printing 14 x 20" concert poster for a benefit for the widow and children of Dr. Martin Luther King, held at the Fillmore Auditorium in San Francisco, CA on 4/27/1968. 
 
 Designer/photographer unknown, medium-thick flat vellum stock poster is in very good to excellent (B/B+ to B+) condition; there are tack holes in all four corners, along with a bit of mild paper toning, a small scuff mark/scrape in the upper right margin, light handling wear, a couple of tiny corner-tip bumps and a couple of tiny pin-prick spots hiding within the image area (and on the reverse side) otherwise fine.

Fairly obscure early-'68 Fillmore benefit poster, I haven't been able to find out anything about this event... there's a big question mark as to who actually appeared.
