RARE Vintage Polar Bear Pin Sparkling Rhinestone Crystal Brooch

Beautiful uber rare polar bear pin from my private collection - only one I have. He's totally encrusted with tiny rhinestone crystals - he measures just a tad over 2" tall and 1.5" wide. He's also very 3 dimensional with his main torso thrusting outward. The little pads of his feet are enameled - so cool. I've had this one for perhaps 30 years - it's been one of my favorites and I actually did wear this one a few times.  There is ever so slight tarnish as shown in the pictures but nothing major. I prefer to leave this one as is. I tried to find this one on the internet but it's nowhere to be found. I wanted to nail down the exact age but will have to rely on my own memory.  It is the only piece I have of course. There are no dead loose or missing stones and none have ever been replaced.
