Measuring approximately 8 1/2 by 11 inches, this preliminary original art sketch features the work of acclaimed comics artists Kerry Gammill. It is a prelim/concept sketch for the cover to Supergirl #4 (May, 1994). The completed cover as it ultimately appeared is shown for reference but please note, it is not included. This listing is for the original art sketch drawn by Gammill. Please note- this is an actual, original piece of art drawn by hand by Gammill. It is not a copy, print or pre-printed image. It is a one-of-a-kind original! Excepting pack-pulled autograph trading cards, CGC Signature Series, signed Sideshow prints, and like collectibles, all autographed items Vault Collectibles sells were personally witnessed, by myself, being signed by the writer, artist, or celebrity in question. No third party is involved. Further, art sketches – and most published original art I sell – were obtained directly from the artist themselves.
