Many of his works seem to be undated, and for this post, I make little attempt to guess when they were made. However, I did my best to arrange them in approximate chronological order.
From images found on the Internet, Grant's marine art was much better than his early illustrations, though he had the skills to have made better illustrations. Perhaps expectations of art directors in the early 1900s was a factor. His 1930s Saturday Evening Post covers (not shown here) were done fairly well.
Many early illustrations featured pretty women.
Pretty static. I would have been inclined to give the background Rhine castle more emphasis to appeal to a sense of adventure with more to it than holding a rile.
Nice use of shade.
I could find no image of the oil version.
Nice atmospherics here.
Judging by the biplane aircraft, this was probably made before 1941.
Although the pose is similar, this photo was World War 2 vintage because the tripod foremast has been changed to accommodate radar.
A World War 2 painting. The positioning of the carrier, destroyer and cruiser is wrong. So is the perspective. If this were reality, a three-way collision was in the offing. Chalk it up to artistic license with the goal of dramatization.
