Frank P. W. "Chip" Bellew was son of the famous cartoonist Frank Bellew which made it natural that he would become a "chip off the block" and follow the career of cartooning. Even while both were still alive they were mixed up in the newspaper columns. "Chip" illustrated numerous books and contributed cartoons to Puck and Life in the days of the Gibson Girl. "Chip" died in 1894. His speciality was drawing canines and both these samples are from July 1886. The masthead on The NY Comic Weekly is in a different style and looks to be signed on the train J. Sharp.
