Stamped Metal
Do you have any information on metal earrings with 639 vintage stamped on the back?
I have a pair of earrings of vintage metal that has three numbers on the back. The numbers are 639. The lok like the Art Deco era.
Hmmm, it does sound quite interesting. Try http://www.google.com or http://www.ask.com. Also, you can check Ebay and see if anyone else is selling earrings or other items similar to yours. Try http://www.wikipedia.org Search and Art Deco Era, maybe you will find information there as well.
