The poor quality materials commonly used in commercial mounting and framing can seriously damage photographs, especially gelatine silver prints. Such prints are particularly vulnerable as the finely divided silver, which forms the image, has a huge surface area so is chemically very reactive.

During the summer of 2019, while we were going through stereo cards and photographs at Bruno Tartarin’s professional premises, my assistant Rebecca drew my attention to a photo album she had just leafed through and which had awakened her interest.

Since my teenage years, I have always been fascinated to seek out the earliest photographs of the cities I visited to understand what the cities used to look like and how they developed into what they are today. This was normally achieved through books. Naturally when I arrived in Jakarta in late 1989, I sought out books containing early photographs of the city.

We travelled slowly down the narrow coastline from Hanoi in the north, to Saigon in the south. On the walls of a number of coffee shops and restaurants, along the way, enlarged coloured French postcards of early-1900s local scenes and portraits were often displayed - suggestive of Vietnamese people’s latent interest in the visual history of their country.

My father, Erwin, came to New York in July 1939 to advance his photographic career.
