Here we are, first images up. I think the best way to do this is to simply have the image with the artist's name underneath. Liiiiiike:

Anthony Kelly, collage.

Robert Ryan, pen and paper.

I stuck in the medium as well, so give me a note if you would like that to be included with yours.

Hope this clarifies what we are after. Anything square, essentially. 

Yaaaaaaaaaaaaaaaay!!!
