The official words are:

We place no restrictions on HAND STAMPED usage, even if for profit. Buy our stamps and use them! I guess 100 Proof Press is what they call an "Angel Company." But we aren't angels. Not remotely. We don't look like them, and I never wear white.

Mechanical reproduction of a HAND STAMPED image is permitted for personal use only. This means if you stamp the image and enlarge or reduce it on the copy machine, that's okay for your personal art stuff.

We do occasionally approve mechanical reproduction for really neat, creative ideas. Please call for permission.

Images from the catalog or the website, however, may not be reproduced in any manner. Mind your manners.
