Portrait of Martinsen (1928) by Olaf Christoffersen is a historic photograph from Asker. The image shows Christoffersen’s father-in-law, who came from a farm in the Billingstad forest area. Martinsen ran the coaching station at Nesbru—the first house in the area—located along the King’s Road (Kongeveien), the 17th-century main thoroughfare connecting Christiania (today’s Oslo) with Bragernes (now Drammen). As a blacksmith, shoemaker, and host for travelers, he played an important role in the local community. The portrait was exhibited at The London Salon of Photography in 1930 and at Oslo Kamera Klubb’s 25th-anniversary exhibition in 1946.
