I'm passing along a request for mail art from a mobile art gallery in New Mexico.
Here's the info I got via email:
Axle Contemporary is an alternative art space located inside a mobile
gallery. We have been in operation since 2010. We are presenting an
exhibition featuring 5 artists working within the context of mail
art called "Priority Mail" opening July 29.
In addition to the exhibition we would like to have an ongoing open call for mail art during the 30 day exhibition.
