This piece is based on one of those now anonymous portraits of wealthy townsmen from the northern Renaissance. What separates this man from his fellow Flemish merchants is a remarkable ability to stretch his epidermis to considerable distance.

People born with this condition generally also have rather unusually flexible tissue in their joints, which enables them to perform feats of contortionism more easily than the less pliable among us; hence, they were commonly called "the Rubber Man" or some such thing. Perhaps this ability would have aided this fellow in selling tulip bulbs.
