An impression of William Gibson's device, comprising two pairs of feathering wings actuated by the arms and legs. Whether the gentleman modelling the apparatus is based on Gibson himself remains unknown!

The engraving of the July 4, 1868, issue of the Illustrated Times. John Stringfellow’s triplane is suspended on its wire, with a canvas sheet to arrest it in the distance. In the foreground on the left is William Gibson’s “aerial apparatus”. In the background, from left to right, are an assortment of kites, Duncan McPhail’s Aerial Steamship, Kaufmann’s model of his “Airmotive Engine” and George Ansell’s fish-shaped balloon. At bottom right is the car of Henson and Stringfellow’s Ariel model. Both of Stringfellow’s machines are incorrectly shown with shaft drives to their propellers.
