I have a plastic file box that I carry my gaming books and materials to the game shop every week. Anytime I come across a sticker I like, particularly if it is sold by the artist who designed it, I pick one up and put it on my DMing crate. This week I got a cool sticker from Beware The Wizard, who also sells hand drawn dungeon maps and apparel. Jake sent a business card with a dungeon on it and a hand written thank you note, a very nice touch. Thanks Jake!
