This miniature cast sterling silver polar bear is just an exquisite little object, happy perched most anywhere or carried in a pocket as a good luck charm.  Though I have found no mark on it, I have found a number of lovely cast silver polar bears online of about the same size and to which it bears a close resemblance. I found this one at the estate sale of an avid art (and small animal) collector in Kansas City, which included many fine things. I've polished it up just a bit, but it could be polished further.

This bear is in excellent condition. It measures 1 7/8” long x 7/8” tall x 1” wide.
