This fun Christmas tree is a Hedison design. The tree has sections of green, red, and pale yellow outlined in polished gold-tone metal. There is a star at the top and a textured gold-tone trunk. The brooch has the Hedison mark on the back. That mark is an H inside a heart with the ©.  The brooch measures approximately 2” x 1½” at its widest part and is in excellent vintage condition.
