I found these prints among my parents papers. I remember seeing them when I was younger and I asked my mother about them. She said they were her mothers (Anna Bartels) and I inquired who was the painter. She said it was "a cousin" The pictures are scenes in Hamburg, Germany
The man was Helmut Clausen. With my research I found that Helmut was a first cousin of my mother. Helmut's father was married to my grandfather's sister, Lily Schridde. Helmut's fathers name was Fritz Clausen.
I did a Google search for his name AND artist but did not find anything on the Internet. I have the prints matted and will find somewhere to hang them in my house.
They are all shades of blue and gray. I wondered if those were the colors he liked or if Hamburg is gray most of the time. The interesting part is I also do watercolor painting as a hobby. I plan to start painting again after retirement.
Will post more in this series later.
