He was an original board member of the Rhode Island School of Design in 1878. In 1880, Bannister joined with other professional artists, amateurs, and art collectors to found the Providence Art Club to stimulate the appreciation of art in the community. Their first meeting was in Bannister's studio in the Woods Building at the bottom of College Hill. He was the second to sign the club's charter, served on its initial executive board, and taught regular Saturday art classes. He continued to show paintings at Boston Art Club exhibitions, as well as in Connecticut and at New York's National Academy of Design, and exhibited "A New England Hillside" at the New Orleans Cotton Exposition in 1885. There, Bannister's work was segregated and ignored by the judging committees. With that experience in mind, Bannister decided not to submit any works to the 1893 World's Columbian Exposition since they would have to be pre-judged in Boston before they could even be sent to Chicago.
