Original 1st printing 11 x 17" concert poster for P.F. Sloan appearing with Magic Fern, the Jimmy Holden Quartet and Bobby Baker at Eagles Auditorium in Seattle, WA on 7/9/1967. 

 Artist unknown/not credited, image is featured on page 37 of Scott McDougall's 2015 book "Split Fountain Hieroglyphics" (SFH 045).

 Medium flat index stock poster is in decent/used (B/B-) condition; there are staple holes with tiny drag tears in the upper left corner, bottom left and bottom right corners (and a tiny pair hiding in the "ag" of "Magic", along with a 1/2" diagonal nip out of the top right corner tip (staple pull), plus a fair amount of toning, a fair amount of moisture staining (numerous tiny splatter discolorations- this one REALLY looks like it was displayed outside in the rain) and a decent-sized set of tape pulls on the reverse, otherwise OK... it has survived for almost 50 years in reasonably decent shape, considering what it has been through.  

 MEGA-obscure Eagles Auditorium concert poster from mid-1967, this is the first one of these I have ever seen.
