Frome's original sketches of Kingston, Ontario, Canada, numbers 187, 189-91 and 196 were sold to the Agnes Etherington Art Centre, Queen’s University, in 1975. Photographs of these sketches are stored at RCMS 40/3/15-19. Glass plates which had been made from several of Frome’s drawings of the Rideau Canal (missing when the collection arrived in Cambridge) have been reproduced on Cambridge Digital Library as Y3062T.
