Charles A. Brooks was one of the USA's finest vignette
engravers; his career lasted from the late 1930s to the mid-1960s. In my opinion, one of his greatest talents was his ability to engrave depictions of sculptures; here are images of three examples of Brooks's skill in this genre, along with photos of the relevant artworks.
