C. 1989/1990 ORIGINAL 15 &1/4 x 11&5/8" pencil artwork on tracing paper by the inimitable Rick Griffin. 

 Unknown exactly what this piece was for, but it's definitely a dense/wild image- the photo of the piece should pretty much speak for itself. There are a good-sized trio of tears in the right margin (the largest is about 4", it goes from the right edge to just above the cat's head on the right side of the image area), along with irregular/hand-torn edges, mild/light toning, a few thin bends here and there... a letter grade is irrelevant in this case, as it is a one-of-a-kind original piece of production material, but overall the piece is in decent shape.

 REALLY cool-looking late-'80's Rick Griffin ORIGINAL mechanical, right from the artist's studio!
