Series of six carte de visite portraits by August Sachtler

This is part of a series of small carte de visite format portrait photographs by August Sachtler, a German photographer who started photographing in Singapore in the early 1860s. The studio details inscribed on the back of these cartes de visite read "A. Sachtler in Singapore", most probably predating Sachtler's partnership with Danish photographer Kristen Feilberg in Sachtler & Co in 1864.
