Paul Signac is a simple painter, chiseling subject matter that was popular and commonplace in his time. As was his life and his paintings - commonplace. He married, left her later, shacked up with a woman, painted some and died.
I have always liked this painting. I enjoy the seemingly random color placement of his work.
"Blessing of the Tuna Fleet at Groix"
1923, oil on canvas
Go see this at the Minneapolis Institute of Arts...
...it is worth a few moments of investigation.
