This is a FOIL Artist Proof for the card, Lathnu Sailback, from the Magic the Gathering set, Aether Revolt.

Each Artist Proof comes signed and numbered on the back, and they are limited to an edition of 30.

You can select an option to have a unique and original sketch on the back. Specify if you have a specific sketch in mind; if not, I will sketch a monster of my choosing.
