Pair of original 1st printing 14 x 21" (appx.) David Singer-designed concert posters for a series of Bill Graham Presents shows held at the Fillmore West in San Francisco, CA from 5/13-16/1971 and from 6/24-27/1971.

 Images are numbers 280 (Humble Pie with Swamp Dogg and Shanti, 5/13-16) and 286 (Moby Grape with Spencer Davis and  Peter Jameson and Flash Cadillac and the Continental Kid,s 6/24-27) in the Bill Graham/Fillmore series.

 Both posters are on medium-thick glossy-coated index stock and have been HAND-SIGNED (in pencil) by David Singer and are in decent/used (B-) condition; they both have a moderate degree of surface wear (the 280 has tack holes, a thin diagonal bend in the upper left margin and a small stain in the bottom margin), both have corner-tip/edge wear and heavy wear on the reverse side (pulls, tape/glue residue, etc...+), but both are still in OK shape.

 While not necessarily investment-level material, they look decent enough for a casual collector, and both are SIGNED by David.
