Every week and a half, for the last 4 or so years, I have mailed a postcard to my grandparents in Jersey. They are amongst the most liberal minded people of their generation and both have an equally cooky sense of humor, so the postcards aren't your typical vacation scene postcard, rather images of 50's nudists having BBQ, a crazed barber with scissors in hand, cats smoking cigarettes, goose portraits, etc. Sometimes I make the postcards myself, but most the time I seek them out. If you have grandparents, send them something. They love hearing from you even if you are a bad person and no one likes you, even if you raped your neighbors cat or pet gerbil, send them a note. It will make their day. Trust me.
In the theme of postcards, I met a lovely lady last week who founded the Em Space Book Arts Center in Portland. She is putting together an exhibition of postcards made by the handy hands of artists everywhere. I shall be participating in this, and if you like, you should too. Here is the submission info.
