Born in Strömstad on Sweden's west coast, Set Uno Karlsson began photographing in the early 1960s, drawn to the documentary power of the camera to capture everyday life with honesty and sensitivity. Working primarily with black and white film, he developed and printed his own work, and over the years his photographs have been exhibited widely and published in several books.

In 1971, Karlsson visited Malta with friends, bringing a 35mm camera and twenty rolls of Kodachrome slide film. He was immediately captivated by the island's vibrant street life, early morning markets, and coastal communities. A day trip to Gozo left a lasting impression-its rural landscape reminded him of his Swedish upbringing, and in a few brief hours he recorded striking images of local life, farming, and tradition.

These photographs, unseen for five decades, were rediscovered when his daughter Maria shared a selection online in 2021, prompting widespread interest. In 2022, they were exhibited for the first time at the Malta Postal Museum, offering a rare and vivid outsider's view of Malta and Gozo in the early 1970s.
