Original 18&3/8 x 10&5/8" (approximately) Rapidograph pen and colored art marker (with pencil underline) artwork on artist's vellum (professionally framed and matted under UV-filtering plexiglas in a hand carved wood frame to 24&1/4 x 16&3/4"), a circa-1965 portrait of legendary Southern California surf band the Challengers by the one and only Rick Griffin.
Artwork has also been SIGNED and personalized "To Richard (Delvy, drummer)- A Good Friend, Sincerely- Rick Griffin" (item was originally obtained from Richard Delvy several years ago).
As this is a framed piece of original art, a letter grade doesn't really apply here but overall the piece is in SUPERB shape- there are a few tiny surface scuffs/ink smears scattered around the image area, a pair of pin holes in the top left/right corners and a few stray pin-prick age spots, but overall it looks VERY sharp for its age (now over 50 years old!)
ABSOLUTELY AMAZING one-of-a-kind pre-psychedelic era SIGNED Rick Griffin artwork, all ready to hang on the wall.
