Turkey – Ottoman Empire postage dues

under construction

1865-1908 issues
Turkey issued its first postage dues in 1863. These featured the tughra/emblem of Sultan Abdulaziz, the same as the regular issues. Beginning in 1865, a star and crescent design was issued. The basic design with denomination was printed in shades of brown for postage dues, the inscriptions printed in the frame color when there is a frame in a second color. This design scheme would be used in following issues with different inscriptions. Those inscriptions may not match exactly due to missing or broken small characters or extra ink flecks.
