The American Weekly was published by the Hearst Corporation (from November 1896 up to the 1963) for inclusion as a supplement to their Sunday newspapers.  It was the Parade magazine of its day, and it was also a precursor of the National Enquirer.  It was billed as having a circulation of over 50,000,000 readers and was filled with scantily clad showgirls and tales of murder and suspense.  It was large - about 21"x15" - and printed on fragile newsprint, so few copies have survived the ensuing decades.  While much of each 12-24-page issue is taken up with sensationalistic photos and text (and even some acknowledged fiction), the illustrations are generally good quality, especially the covers.  Starting in mid December 1922, King Features Inc. syndicated Bonzo's image for this suppliment.  Under the title "A Dog's Life", they were used as the front page of the suppliment & started out by replicating the same images as had appeared in The Sketch magazine.  By March of 1926 Studdy started doing strip cartoon stories for it.  By 1932, after around 115 front covers were published featuring Bonzo, "A Dog's Life" series finished. Here are a few examples of the series:

17th December 1922 - "Why the Dickens did you cut me off"	27th October 1923 - "Bonzo shows the Bonzolines how to do it"	19th July 1925 - "Bonzo gives a little surprise party"
16th August 1925 - "Bonzo catches a crab"	24th October 1926 - "Bonzo gets the reward"	14th November 1926 - "Bonzo and the busy bee"
6th July 1930 - Untitled	10th July 1932 - Untitled	14th August 1932 - Untitled
