The most prominent early publisher of Ottoman postcards. Born in 1852 on the eastern border of Austria-Hungary to German parents, he came to the Ottoman Empire in the 1860s. At the age of seventeen, he opened a framing business at Yüksekkaldırım in Istanbul. It is hard to underestimate his role in the publishing scene that followed.

These cards were printed for promotional and fundraising purposes at different times (1915-1917) but for simplicity I am considering them as a single series. There are at least 24 cards.

Established in 1871 "Kunstdruck-Anstalt Römmler & Jonas" was a publishing house in Dresden, which was known by its printing of architectural photographs. The company was specialized in the production of cityscapes that it systematically had photographed in every major city through local contractors and then printed mostly in cabinet format on paper, books and art prints.

Jacques Ludwigsohn was a postcard publisher in Istanbul (Constantinople) at the beginning of the 20th century. The firm was also known as Ludwigsohn Frères (Ludwigsohn Brothers).

Ottmar Zieher (1857–1945) was one of the most influential postcard publishers of the late nineteenth and early twentieth centuries, active during the formative years of the international postcard boom. Born in what is today Baden-Württemberg, he established his business in Munich in the 1880s and quickly rose to prominence through close collaboration with first-rate chromolithographic printers in Leipzig. By the mid-1890s, Zieher had already issued thousands of richly colored view postcards, initially focused on Germany and Austria-Hungary, before expanding decisively into international subjects. His firm remained active well into the mid-twentieth century, a testament to its commercial success and enduring reputation among collectors.

Issued by Geo Mavrogordato (January 4, 1854 – June 4, 1926), owner of the Tarabya Nursery (Establissement Horticole de Therapia), banker, and painter, these cards often feature rare Istanbul photographs. The Mavrogordato family, originally from Chios, left their mark on Ottoman history and business life for centuries. Among the family was Alexander Mavrogordato, the palace physician and signatory of the Treaty of Karlowitz.

Anton Zellich was a Croat printer from Dalmatia, who began work with Cayols (Henry Cayol and Jacques Cayol who opened the first litho press in Constantinople in 1831) in 1840. Zellich managed Cayol's printing house after Henry Cayol died of cholera in August 1856. In 1869 he set up on his own account. Zellich Fils is the firm form by Anton Zellich's children. One of the sons, Henri Zellich had his own firm as well and printed his own postcards.
