Original early-1980's-era 10&1/2 x 14" art marker/india ink (with pencil underlining) drawing, "How Do You Know You've Been Called?", by Rick Griffin.
Drawn on medium-thick sketchbook vellum (and SIGNED in gold ink by Rick), piece is in fantastic shape; just a few scattered light handling creases, a pencil notation in the lower right margin, a hint of moisture rippling, a small tape pull in the upper left margin and a stray stress bend or two, otherwise fine. The pencil notation (29%) is a production note for when the image was photographed for publication (I haven't found exactly where/when this image was published).
REALLY COOL fully-rendered and SIGNED one-of-a-kind Rick Griffin piece!
