Huck Finn advertising flyer

See a larger version here.

It's curious that the flyer makes it sound as if Tom Sawyer is a bigger part of the story than he is. The flyer says:
In the abstract, the book is the story of the adventures of Huckleberry Finn, Tom Sawyer and a negro named Jim, who in their travels fall in with two tramps engaged in TAKING IN the different country towns through which they pass, by means of the missionary dodge, the temperance crusade, or under an pretext that offers to EASILY raise a dishonest dollar.
The writer follows these characters through their various adventures, until we find the tramps properly and warmly clothed - WITH A COAT OF TAR AND FEATHERS - and the boys and Jim escape their persecutors and return safely to their friends.
