"Portrait of William J. Glackens"
1904
oil on canvas

From the Time-Life book on American Painting 1900-1970:

"The influence of the French Impressionist Edouard Manet left its mark on many paintings by the realists. Henri made no attempt to disguise his indebtedness in the full-length portrait of his friend and fellow artist William Glackens."
