Pair of original 1st printing 13&3/4 x 21" (appx.) David Singer-designed concert posters for a series of Bill Graham Presents shows held at the Fillmore West and Winterland in San Francisco, CA from 12/18-21/1969 and from 6/11-14/1970. 

 Images are numbers 207 (Santana with Grand Funk Railroad and Fat Mattress at Fillmore West and Winterland 12/18-21) and 238 (John Sebastian with Buddy Miles and Rig, 2/26-3/1 at FW/Winterland) 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.

 The BG 207 is in good (B) condition; there are pin/tack holes/wear in the top left right corner-tips, along with a few thin horizontal bends going across the bottom margin, light handling wear, a thin horizontal drip stain in the left border of the interior image area, tape marks on the reverse and a bit of surface wear, otherwise OK. 

 The BG 238 is also in good (B) condition; there is a semi-pronounced horizontal roll bend/wave going through the center of the poster, along with a bit of corner-tip creasing, light handling wear, a series of tiny edge dings scattered around the outer margin area, masking tape remnants on the reverse and a few light surface marks (light rub marks and pin-prick spots) here and there, otherwise fine.

 Nice-looking pair of ARTIST-SIGNED first printing Fillmore posters.
