Vintage sterling silver neckerchief slide from the 1950s. The design is awesome with a Western saddle and a horseshoe. Look closely at the seat jockey, it has a little dog that almost looks like a bear on it! 

It is hallmarked on the back. I acid tested it twice and it is sterling silver, However, I did not want to scratch into the piece deeply and it might be plated as many from this ear were. Measures 1 3/4" by 1 3/8". Weight: 17 grams.
