Nothing is known about this artist except his name, given in the inscription on the National Gallery's painting Bare Knuckles (1980.62.9) as GEO. A. HAYES. The artist was active c. 1870/1885, dates derived from the clothes worn by the figures in the painting. [This is an edited version of the artist's biography published in the NGA Systematic Catalogue]
