This original watercolor would look great in a white frame. This is 12x15 which would frame in a 16x20 frame, with a 2-1/2 inch mat. It is shipped free in the U.S., in a heavy-duty tube, unframed. Shipping framed would be $10 in the U.S.
The choices of framing are (if still available):
.....an off-white 16x20 frame that measures 19" x 23", double matted under plexiglass, and ready to hang with hanging wire (view 2)
.....a brown and gold 16x20 frame that measures 21-1/2" x 25-12", double matted under plexiglass, and ready to hang with a hanging wire (view 1)
