Magic the Gathering Artist Proofs are collectible cards given to the artist, featuring a blank white side instead of the traditional Magic the Gathering card back. All proofs come signed and numbered. Due to my current schedule, I'm unable to take any more sketches or alters for the time being, but cards and merchandise can still be sent as-is! And if you're looking to send your Magic cards to me for signing, please email Mark Aronowitz at Serra3@optonline.net for shipping information and details!
