A Black baby and his dog are aboard a whaling ship. They fall overboard and have a series of mediocre comic adventures.
A series of cartoons from 1927 have just shown up on the Internet in beautiful prints, including this one, with synchronized sound. I have never heard of any of the talent associated with them (although Robert E. Sherwood is credited with writing the titles on this one, which I don't believe) with synchronized sound. Only the presenters make any sense. It is the Weiss Brothers, two ambitious film producers who never got far out of Poverty Row.
Had this shown up credited by Paul Terry working for Van Beuren at the time, it would not have struck me as particularly noteworthy, except for the cleanness of the print.
Later: a brief exchange of email with Tom Stathes indicates that LIFE magazine got involved in movie cartoons and this is an example. That's the humor magazine before it was bought by Henry Luce and turned into a photojournal weekly. This would explain why Robert E. Sherwood wrote the titles: he wrote movie and theater reviews for the magazine.
