After that comment my friend made yesterday about sending postcards to herself I was reminded about all the mail I’ve sent to myself over the years. It isn’t as exciting as you might think.

Anytime I design a card I post one of them to myself. I make sure the date on the postmark is legible. I also sign my name across the sealed flap. I learned many years ago that this is one way to prove ownership of an idea if you are ever challenged by someone who claims that the idea was theirs first. With a firm date to associate with the work (legible postmark on the envelope) and no evidence of tampering (signature across the sealed edge) you can at least prove the idea was yours on that day in time. I haven’t had to crack one of them open yet and I hope I never have reason to.
