I sell greeting cards (blank inside) with matching envelopes, unframed prints, and framed prints. There are a few exceptions, but most of my prints are available in two sizes: medium sized prints are sized to fit an 8x10 frame (11x14 matted,) and large prints are sized for an 11x14 frame (16x20 matted.)
Cards -- $5
Medium Prints -- $20
Large Prints -- $30
Framed Prints - prices vary
(I have some very small framed but not matted prints for as little as $10 - $15. Larger matted prints run anywhere from $40 - $100+ depending on the size and the frame.)
The frames are all recycled. I find most of them in thrift stores. I clean the glass, repaint or refinish the wood and add new hardware when needed.
** Because my art is made by digitally manipulating, layering and otherwise adjusting drawings, there is no such thing as an "original" that can be purchased.
