Starting around 1885, Letitia Hart exhibited her work at venues including the American Water Color Society, Art Club of Philadelphia, Brooklyn Art Association, James Gill's gallery in Springfield, Mass., Louisiana Purchase Exposition, National Academy of Design (she received the Norman W. Dodge $300 prize there in 1898 for best painting by a woman), Pan-American Exposition, Union League Club of Brooklyn, and the Woman's Building at the 1893 World's Columbian Exposition in Chicago, Illinois. With her sister (who often posed for portraits) and father, she commuted from Brooklyn to a top-floor studio at 11 East 14th Street in Manhattan. She and her sister were praised for "the truthfulness and delicacy of their portraits."
