It is made with the superior workmanship expected from Trifari. The classic signature of the "T" with the crown is on the back along with the Pat. After an extensive search, I have been unable to locate the patent number for this design. But since it is marked Pat.
We know a patent was filed and was pending when this piece was made. Therefore, it was made prior to 1955. This beautiful vintage brooch is approximately 1.75" long and approximately 1.5" wide. This exquisite brooch is sure to compliment any sweater, scarf, jacket or little black dress it is worn on!! It is perfect for work, date night or any special occasion! Makes a beautiful gift for a birthday, Mother's Day. Holiday or any occasion to make her feel special! This vintage piece shows no sign of wear. An absolutely incredible vintage piece! This is a "must have" unique piece for any Trifari collector!
