Here’s a pair of the assemblage pieces I worked on a thousand years ago or so…
Both are for sale–fishy is about 4 x 5, the mannequin is 5.5 x 6. Both have hangers and can hang as is, or could probably be mounted into a shadowbox-style frame.
ETA: Okay...owing to unexpected interest, the mannequin is going to e-bay! Starts at $25, check it out!
RETA: ...and the fishy, too. Auction Listing!
