advance car is," said Phil after he and Billy had sat down beside
the tracks.

"It would take all night to do that, but I'll give you a few
pointers and the rest you will have to pick up for yourself.
In the first place an advertising car includes billposters,
lithographers, banner men and at least one programmer."

"Sounds all right, but it doesn't mean much of anything to me,"
laughed Phil.

"The billposters post the large bills on the billboards, and
anywhere else that they can get a chance, mostly out in the
country and in the country towns. In places where there is a
regular billposter, he does that work for us. Any boards not
owned by a billposter, or a barn or a pigpen or a henhouse on the
road is called a 'daub.' At least two tickets are given for every
place we put a piece of paper on. These tickets are numbered
and signed. Now, if a fellow out in Kankakee, we will say,
should chance to tear down the bill, when he presented his ticket
at the gate on the day of the show, it would be refused.
He'd pay or stay out."

"But how would they know he had taken down the poster,"
questioned Phil.

"Checkers follow along at intervals and check up every piece of
paper we put up. We send the record of our work to the car back
of us and they in turn send our and their reports to the car
behind them."
