[The Australian Panther]

Doesn't say so up on the index card, but this is early George McManus. [Bringing up Father] I thought I recognized those feet.
[n 1904, McManus created the first American family comic strip, The Newlyweds, about an elegant young couple and their baby Snookums. The popularity of the strip prompted the management of The New York American to invite McManus to work for their newspaper, which he did from 1912 on. Renaming The Newlyweds as Their Only Child, he continued that strip and began other daily strips: Rosie's Beau, Love Affairs of a Mutton Head, Spareribs And Gravy and Bringing Up Father.]
