Original 1st printing concert poster for Santana Blues Band with Erma Franklin and Frumious Bandersnatch at the Carousel Ballroom in San Francisco. This was a three-day event held on April 19, 20 & 21, 1968. Steve Catron designed this great-looking psychedelic poster. The art on this is often compared to his Grateful Dead poster the Berry Dropper. Printed on medium-thick flat index stock and measuring approx. 15" x 22 3/8" there are no tears, tape or tack holes, there are some bends and light crease along the top, a few dings and discoloring to the edges. The colors are still bright and vivid. This poster is a hard one to find in any condition!
