1954: When David Hockney studied art in Bradford, he would often visit The Sea Catch fish and chip shop near closing time to get a cheap evening meal. One of his early artworks was a lithograph of the chippy, depicting the proprietors, Hayden and Janet Smith, frying and serving, while a young man leans on the counter. Hockney made only a handful of copies, one of which he gave to the Smiths, who displayed it for several years above the fryers. In 2017, it sold at auction for £18,750.
