I received my first response to the mail art I sent out in December! I selected the addresses by searching random cities in the US on Google Maps, and then using Google Streetview to 'walk' down streets until I saw a house I liked. When I received my response, I was feeling particularly downtrodden because also that day I got back 5 of the letters I'd sent, saying there was no such address (which I was somewhat expecting, since addresses on Google Maps are approximate). But lo and behold there was a letter from Mimi, of Minneapolis, Minnesota! By a happy coincidence, Mimi is an artist as well, and sent me some beautiful cards! This was exactly the kind of response I was looking for through this project. I hope someone else writes back too. I re-adressed the letters that were returned-to-sender, and they are headed out to spice up the postal system once again.
Here is what Mimi sent me:
