This project was born of a missed opportunity.
I read an article about the publication of the panels of the Doonesbury cartoon that were printed as a series of postage stamps, and how viewers had cut the panels out of the newspaper, glued them onto envelopes, addressed the envelopes and dropped them into a mailbox.
They were subsequently delivered, with cancellations! It seemed such a wonderful subversion. Taxation with someone else's representation.
Weeks later, while thumbing a national news magazine, I found myself staring at a cartoon stamp with Bugs Bunny, ears protruding beyond the frame, over sized, just the thing...
I promptly cut the image from the page, affixed it to an envelope and dropped it into a mailbox.
It arrived the next day. Cancelled. I was hooked.
