Here’s a World Color Printing strip that ran in their Sunday section from January 1 through April 9 1911. Biograph Bill was one of a legion of strips about the movie-making business, but a pretty early example of the genre. The strip was unsigned throughout its run, as were quite a few World Color strips during this period. I think the reason for much of it is that cartoonists otherwise gainfully employed for major syndicates turned out these strips on the side, perhaps in violation of their contracts. The art on Biograph Bill is profession though unremarkable, and I doubt that anyone could pin down the creator based on the style.
