Here’s a Sunday feature, simply titled Pete, produced by Everrett Lowry for the top of the line version of the McClure Syndicate Sunday section. Pete the monkey, sort of a simian Katzenjammer Kid, plays pranks on his dull-witted keeper. The unassuming feature was rarely, if ever, given the outer wrap full color treatment.
I have the strip beginning on December 27 1903 based on the San Francisco Chronicle, oddly enough with two complete strips appearing in the same section, while Alfredo Castelli cites a start date of December 13. The strip last ran on June 25 1905.
Thanks to Cole Johnson for the scans!
