Think some of you may be interested in the following, I think it is a neat way to show your original work ...
Struts Gallery - 8th Annual Mail Art Show, May 2 -May 24. Mail in one or more artworks, the only limitation is that it must be sent via the postal system. Pieces may be sent to Struts from now until the end of the show. The works will be installed in the same order in which they are received. Just stamp it and send it to Struts Gallery at 7 Lorne St, Sackville NB E4L 3Z6 Canada. If you would like your piece sent to another artist please indicate this when you submit your piece. If you would rather it be returned to you, then please send, along with your piece, a self addressed stamped envelope to the Gallery.
