Signed Framed Mixed Media 3D Art - Looks like Topographic Map of Sea of Japan ?

This is a signed framed mixed media 3D art piece that resembles a topographic map --- perhaps an impressionist take on the Sea of Japan? It features a unique artistic style and the media (perhaps, clay) adds depth to the piece. The frame has a number of dings, nicks, and scratches. Roughly 11 x 9" framed.
