Perambulating Press Prints On Paving

THERE have been sandwich men, sound trucks, and sky-writers to carry advertising messages before, but it was left for a Spanish inventor to devise the perambulating printing press for making bill boards of the pavements.
The entire press is no larger than a baby buggy, and is no more difficult to push. Paint which dries upon contact with the pavement is used instead of printer’s ink, and the advertising message may be walked upon immediately after application without tracking. The machine made its first appearance in Barcelona, Spain.
