What a great find. I always loved MTG for the artwork. I played very sporadically, and didn't really have an awesome collection, but I sold all my cards a few years back. Everytime I see posts of the artwork like this, I start to miss it again.

All art has intrinsic value, but the fact that this artwork can also be used a part of playing a game makes it even cooler.

I'm sure you'll cut a profit on this without any worries!
