This is a vintage porcelain or glass brooch. It has a picture of a dog on it, which I believe is some type of spaniel or setter. The brooch is not signed and I do not know who made it. It measures 1-1/4 inches wide and 1-5/8 inches tall. It is in good condition but may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
