For my annual personal holiday card, I went with a concept I had come up with years ago but had never had a chance to actually create; a clear postcard. Calling it the "world's first completely crystal clear postcard," I printed the card double-sided on clear transparency. Due to the double-sided printing, certain elements appear backwards on the reverse side, but everything is designed to fit together regardless of the side you are looking at. Almost all of the cards made it through the mail to their destinations, although in various stages of "decomposition."
