The fine folks at Indieink.org have seen fit to publish something of mine, a piece of fiction called "A Picture Postcard". You can read it here. It is based on, you guessed it, a picture postcard. The card was written in 1981, and the story written here is about the back story of the characters mentioned on the postcard. I found it in a paperback collection of Kafka I bought at a used bookstore.You can look at the postcard here, if you wish.
I think it's pretty good, myself.
