We received a postcard last week. It looked fake -- or, at the very least, salesy. But in fact it was a picture of some friends, taken by the Thames in London, by a machine or a kiosk or a service that obviously specializes in automating the sending of personalized postcards. The note, clearly written by our friend, was printed in a font evocative of handwriting but obviously not. I imagine that there was some kind of setup with a sign, "Take your picture, write your note, and we'll print and send your postcard anywhere in the world!"
