Goodman Games

I just got an envelope with some monster alphabet bookmarks.
The bookmarks are nice, but the illustrations on the envelope are brilliant:
- tentacled beastie with litter squishing some adventurers
- wizard writing a nasty letter to his colleague
Unfortunately there is an address sticker across the tentacled beastie:-)
Are these illustrations unique, or are they somewhere in a book?

For a couple of years now, Goodman Games has been doing special art for their boxes and envelopes. I think it's all specially made just for that stuff.

Drat. I suppose I'll have to try to steam those stickers off then...
