An ink portrait notable for the most decorative hat in the collection — a brimmed hat with a feather tucked into its band. The feather is described with Sidney's most naturalistic mark for a decorative element: the central spine, the branching filaments, the way it sits in the hat band with its stem secured and its plume spreading. This feather is drawn the same way Sidney drew actual feathers in the Naturalist's Table (771) — the same kind of close, specific attention.
The face below the feathered hat is seen in three-quarter profile — strong nose, small mustache, the jaw set. The eyes have a quality of alertness beneath the hat's brim. The overall impression is of a man of some personal style — the feathered hat not a utilitarian choice but an expressive one.
The jacket and collar below are described with loose marks, the hatching of the jacket's texture rapid and gestural. At the right shoulder, the collar's opening creates a light zone against the darker jacket marks.
The hat series in the portrait collection is now substantial: flat caps, fedoras, bowlers, caps, berets — Sidney drew people in hats consistently across many sessions and periods. The feather distinguishes this one from all the others.
