The exhibition highlights the works produced using airbrushes to create large colourful images on the fairground rides.
Keaton added: “The artists are little known and not much respected in the art world. Most of the artists are completely unknown.”
The brothers said they had visited the fair often as children and they dedicated their first joint work to the showmen.
George Brignall McDougall said: “This is their life’s work which we merely documented. Without them and the artists they employ none of this would exist.”
He added the archives of fairground history were limited and the showmen of Hull Fair had welcomed the project and answered any questions.
