Most work should be available for purchase on the site. 

Pastel works on half-sheets (22x15") run between $800-$1500.
Pastel works on larger sheets run between about $500-$2000.  The price can be lower on larger sheets due to the lack of pigment used to cover the surfaces.
Oil works run between $1000-$4000 depending on size and content.

The Slug requests personal contact emails from all interested parties.

Should you instead wish to purchase some of the more mundane versions of the art on this site, please visit my cafepress and imagekind sites for prints or apparel.  My pastels make excellent mugs!
