This ring is not dated but it is believed to be from the 1960s or 1970s and used as a prize in an old gumball machine. The flicker has two different images of Dr. Strange. The ring is made of plastic with silver paint. The flicker is simply marked:
DR. STRANGE
To judge the size the ring face measures about 1/2'' x 5/8''. It is in mint condition as pictured.
