Adolph Friedländer (17 April 1851 – 7 July 1904) was a famed German lithographer of posters and a publisher hailing from Hamburg. His printshop produced over 9,000 posters between 1872 and 1935, predominantly for artists, magicians and circus and vaudeville performers. First learning lithography at his father's shop in Hamburg, he received formal training in Berlin and returned to operate independently in 1872. First concentrating on labels for businesses, he turned to poster printing to cater to the many artists and performers which operated nearby to the location of his business.
