Anson Maddocks Art also offers a print of this image here:
Dragon Engine Fine Art Print
From the very first Expansion set of MTG artist proofs made available (as no artist proofs were made for Arabian Nights); Antiquities was released in early 1994.
This artist proof will be signed on the front by Anson. If you wish to personalize your artist proof collection or enhance your investment, you may choose to add custom artwork to the blank back side.
Other versions available:
Dragon Engine - 3rd/Revised Edition
Dragon Engine - 4th Edition
