This is an oil study, a preparatory sketch often done by an artist when preparing a large canvas. In addition to one or two photography sessions, if the subject cannot pose from life, some charcoal sketches are done so the artist has an opportunity to get to know the subject's character and expression.
In this case, Hart was looking for elements of color, dynamic energy in the turn of the head and shoulders, the suggestion of potential movement, and Mr. Abboud's striking gaze and intensity of character.
