This is a Vintage unsigned Hattie Carnegie Figural Brooch from her well-known "Primitives on Parade" line that was said to be designed by Kenneth Jay Lane. This is a Dog, I believe a Scottie(Scotty) with a Wonderful Lemon Yellow Frosted Body and Head in Gold tone, with a Red-orange Rhinestone Eye and AB stones Collar.
The Brooch measures 1 3/4" x 1 1/2". It is in Very Good Vintage Condition, with a little wear to Gold tone, like the tip of ears.
