I have scoured Dr. Wattenmaker’s writings on both Pascin and Demuth; I have scrutinized every footnote. Yes, Demuth knew and borrowed visual ideas from Pascin, but these two pictures suggest he might have set out deliberately to use Pascin’s Cuban Hospitality as a starting point.
Research did not verify my suspicions. A librarian at the Barnes Foundation told me the1915 Pascin was acquired by Dr. Barnes in 1921. The Demuth, painted in 1919, does not have an acquisition date. If Demuth saw this Pascin painting before it reached the Foundation in 1921, Pascin would have had to show it to him since there are no other references listed for it before a 1921 exhibition—the same year it was acquisitioned by Dr. Barnes.
