This is a fascinating example of the presence of ethnic Germans living in Baku, Russia, in the early 20th Century! This red, 3-Kopek postal stationery card(in very good condition, and quite clean!) was sent within Baku(nice cancel!) on March 7, 1912, by a Doctor Tiedemann, a member of the, Reich Germans Association! He was notifying the addressee that the next meeting of the organization would be on Thursday, March 21, 1912, from 8A.M.!
