Norman Ritchie (who signed all his work 'Norman', with long tails on the Ns) was a fixture at the Boston Post for decades, but to my knowledge Mr. Baffles was his only continuing feature. It ran only during 1906, and I don't have exact dates as yet because my research is not yet finished.
Mr. Baffles concerned itself with lampooning Boston life, especially the politics of Beantown. Norman showed an unexpected flair for design in his Sunday pages, and it's too bad for us that most of his time at the Post was spent in producing somewhat run-of-the-mill editorial cartoons.
