Grateful Dead - Wake of the Flood - album cover proof - Rick Griffin

20 x 26.5 sheet, printed both sides.  This is a 1973 proof sheet or "make-ready" for the production of the album cover for Wake of the Flood.  Art by Rick Griffin.  On the front is a full color proof, and the back is blue and black only.  A nice "back room" item for Rick Griffin and Grateful Dead collectors.
