Perfect Form, Long and Low c. Mid Century Brass Mouse

I've seen little vintage brass mice with spike tails used for punching and holding receipts but this, nearly 10 inches long and with perfectly proportioned, perfectly minimal (but yet very mouse-like) form, is quite a different thing--feels closer to a Carl Auböck!  Excellent on a desk but I'd argue better treated as a sculpture, laying long and low across the edge of a shelf, say. Marked Japan on one edge of the underside, mid 20th century or a little earlier I believe. Love. 

 9 11/16" l x 1 5/16" t x 1 1/16" w. Very good condition, nice warm patina to the brass. One patch of surface wear to the back side lower center of the body as shown--not rough and just general wear, I don't think at all detracting.
