This is an Official Marvel Comics ONE OF A KIND ORIGINAL COLORIST'S ART COLOR GUIDE PAGE, and it was used in the direct production of the vintage THE INCREDIBLE HULK issue 309 comic book from 1985, featuring the rampaging Hulk (from the Avengers). This is the ONLY color guide of this 1980's page in existence (it's 1 of a kind), and it was used in the production of the actual published comic book. This 80's Hulk story featured art by Sal Buscema, and the Marvel Colorist for this issue was Bob Sharen.

SIZE: This 1 of a kind Marvel color guide art page measures about 11 inches by 8 1/2 inches, which is normal for colorist's artwork.
 
NOTE: Color guide artwork is different from black and white original art. Color guides (colorist's artwork) are re-sized copies of the pencil and ink original artwork that are assigned to the issue's colorist, and then hand colored by that colorist. Colorguides usually measure about the same size as the published comic book, and some have "color codes" for the printers to follow. Because most modern comic books are now colored by using computers, there are no more color guide pages being produced, which makes the surviving color guide pages highly collectible. J98854.
