I am listing my coloring book "Gardens & Goddesses" with one page colored (Orchids in the Rain) and signed at the Monthly Fantasy Art Auctions group on Facebook. This is a special one-of-a-kind item available only through this auction. (And I don't list my stuff in auctions generally... ever.)
Anyhow, if you're interested, the listing is at Monthly Fantasy Art Auctions group on Facebook. Everyone is welcome. Just send a request to join and one of our administrators will approve your request.
Here's the direct access to my coloring book listing. You can place your bid in the comments.
