art card

Last year and the year before I was really into art trading. Especially when it came to atc's. But so far this year has hardly brought any trading at all. I am simply too busy with other stuff. However, last week I read the book "Good mail day"  and it got me thinking about mail art again. So I couldn't resist making a little art card. Here it is:

It was simply fun making it. I may send it to someone or keep it to make prints of. But would it then still be mail art I wonder?
