At the time the photograph was taken, the painting was on public display in Viðeyjarstofa in Viðey. A plaque explains that it was a gift to the City of Reykjavík from Eimskipafélag Íslands on the occasion of the 200th birthday of Reykjavík (which was in 1986). The plaque does not give any information about the artist but a quick Googling for the signature "P. Raadsig" and "Ingolf" reveals the name of the painting and information about the artist.
The picture was taken under natural lighting with a hand-held digital camera. The right side of the painting was placed closer to a window when the picture was taken. These factors contribute to the mediocre quality of the reproduction.
