Artwork by George Pratt originally prepared for the book 'Voodoo Child,' but ultimately unused, including nine prints (all about 17 x 22), some with original tracing sketches on the reverse, plus an original pen-and-ink drawing of a seated Jimi Hendrix on an off-white 11 x 14 sketchbook page. Also includes a 20 x 29 poster for the book, written by Martin Green and illustrated by Bill Sienkiewicz. In overall very good to fine condition.
