This cabinet card features a handsome young man, probably from the City of New York. The imprint reads: Rud Bachmann, 6 East 14th St., New York.
The photographer was likely Rudolph Bachmann, born about 1850 in Switzerland.  He came to the U.S. about 1880.  By 1884 he was running a photography business at 1437 Broadway in New York and remained at that location until 1892.  From 1892 to at least 1922, the business was located at 6 E. 14th Street in NYC.  From 1914 to 1922 most directory listings note “& Son” when referencing the business. 
Since cabinet cards were produced from in the late 1800s through the 1920s, and given the address of the business on the photograph, it can be assumed that the photograph was taken between 1892 and 1920s. However, cabinet card popularity began to taper off in about 1905, so a better estimate is probably 1892 to 1905.
