Approx age of postcard 1912.  I'm not sure if this is a RPPC.  When you turn the card from side to side, it has the silver tin-type two color look.  HIGH CHIEF Chyenne & LONE BEAR Souix.  Back of postcard is The Osage Post Card Co., Fairfax, OKLA.

Unposted.  Mild age discoloration. 

From my grandmother's collection.

Will be listing more postcards.  Vintage and antique items - brand new items too.  Books, cookbooks, Barbie, Starbucks, Ina Garten note cards, jewelry, dishes, +++.

Please come back often.
