I picked this from an estate sale I was working at. It was nicely framed at the time. The owner was a former German WWII German soldier, likely an officer. His home was full of Dutch Impressionist paintings, a small library of nazi related books, a fair amount of high end glass and ceramics, numerous prints and this one on the wall above a small desk.
I have assumed that it's a student's copy of a study from a Giovanni Benaschi painting. The paper is well aged, laid paper. The work is stunning in it's detail. That's all that I know at this point. For more on the artist: https://en.wikipedia.org/wiki/Giovanni_Battista_Benaschi
