Being a lover of pottery (but not a creator of it myself, yet) I enjoy the distinct mark of the potter. Since I prefer not to have my signature interfere with the graphic design nature of my corrugated sculptures I've created a mark based on my "R" brand logo. Hand-carved from a soft white eraser this little "R" is the final step before the artwork is complete. All pieces I've created so far (35 in all) have this mark. But not to be replicated, each piece is also signed on the back.
