No other works by C. F. Senior, who signed his name so prominently and clearly in the corner of the National Gallery's painting The Sportsman's Dream (1980.62.21), have ever been discovered. He is believed to have been active in 1881 or later. A genre painter by the same name is listed in Lipman and Winchester's Primitive Painters in America as active in 1780 in Reading, Pennsylvania. To examine the possibility that the numbers in the Lipman and Winchester date were transposed and that this artist might have been the maker of the National Gallery painting, several sources in the Reading area were consulted. No person by that name was found. [This is an edited version of the artist's biography published, or to be published, in the NGA Systematic Catalogue]
