This pin or brooch is made of metal (perhaps stainless steel or pewter) and acrylic with an encased petal that creates the look of a jack-in-the-pulpit flower. I believe it is handmade. It is fairly heavy for its size so needs to be worn on fairly substantial fabric. The Lucite is sort of clear lemony yellow and the petal is light celery.
Condition is excellent vintage. No problems.
The brooch is 2 inches long.
