The first company to publish D'Ancona pin-ups, about 1935 to 1937, was Louis F. Dow in St Paul. D'Ancona worked in oil on canvas and his originals from that time usually measured about 30 x 22 inches. His early work is comparable in quality to that of the young Gil Elvgren, who had begun to work for Dow in 1937. Because D'Ancona produced so much work for Dow, one might assume that he was born in Minnesota and lived and worked in the St Paul, Minneapolis area. It is known that he supplied illustrations to the Goes Company in Cincinnati and to several soft-drink firms, which capitalized on his works similarity to the Sundblom/Elvgren style, which was so identified with Coca-Cola.
During the 1940s and 1950s, D'Ancona superb use of primary colours, masterful brushstrokes, and painterly style elevated him to the ranks of the very best artist in pin-up and pin-up art. His subject matter at this time resembled Elvgren's. Both enjoyed painting nudes and both employed situation poses a great deal. D'Ancona also painted a fair amount of evening-gown scenes, as did Elvgren, Art Frahm and Erbit.
By 1960, D'Ancona had moved into the calendar art field. Instead of doing pin-ups and glamour images, however, he specialized in pictures on the theme of safety in which wholesome policemen helped children across the street in suburban settings that came straight out of Norman Rockwell.
