I am so in love with these earrings....I have never seen anything like them! On the back of the pig's head and body it says copyright JJ. I believe them to be from the 1980s. They are made from pewter like most JJ cosmetic jewelry. The earring stud is the pigs head and arms and the earring back is the pigs dangling body. It has a super unique effect...like the pig is hanging on your ear. They dangle a total of 1.5 inches in length. They are very comfortable to wear and they don't tug on your earlobes.
