Danube Steam Navigation Co in Constantinople 1843 (March 9): Entire letter from Constantinople to Gemlik on the Sea of Marmara with an exceptional fine strike of the circular "D.D.S.G. / CONSTANTINOPLE / P.P." in greenish blue (Tchilinghirian fig. 441). This postmark is mostly found blurred, this example being unusually well struck.rnNote: ​ In 1829, the Donau-Dampfschifffahrts-Gesellschft (DDSG) was founded. It supplied postal services on the Danube as well as on the Black and Aegean Sea. In 1845, the DDSG services were restricted to the Danube and Odessa.
