Mark Osman Curtis was a Scotsman who moved to Denmark just before World War 1. He was somewhat of a hermit and was almost frantic about keeping his personal information a secret. Despite this seclusion he is nonetheless known by virtually every art dealer in Denmark. He, however, obviously found better comfort in the company of domestic animals, especially cows. Thus his preferred choices of subjects were village or meadow scenes with cows. Curtis’s portraits are few and far between.
