This Mamselle inital U pin or brooch is on it's original display card. The card is marked MAMSELLE with the Eiffel Tower in front of it. The pin is marked "c" MAMSELLE on the back. The U pin is heavily textured and has bright stylized leaves cut on one leg of the U.
Mamselle was the trademark of the B. B. Greensberg Co. The Mamselle trademark was first used in 1962. The Mamselle with the Eiffel Tower trademark was first used in 1968.
This pin is in mint condition. I doubt that it has ever been worn. The display card does have some wear to it. The pin measures 2" X 2" and is on a 2 3/4" x 2" card.
