Abstract: A mobile promotional vehicle includes a tractor cab having an elongated, substantially horizontally extending bed connected thereto. An information display superstructure extends upwardly from the bed and includes outwardly leaning side walls which diverge upwardly, and converge as they progress from the rear of the bed forwardly in the direction of the cab. These side walls are joined by a horizontal, trapezoidally-shaped top wall, and by vertically extending, trapezoidally-shaped forward and rear walls. This allows the outer surface of the side walls to be better illuminated and more visible. Multiple display panels are stored inside the side walls and can be quickly transferred to an exposed, display position in juxtaposition to the outer surface of the side walls.

Abstract: A bicycle handlebar stem is made of two separate parts, a tubular shank and a gooseneck. This eliminates or substantially reduces long drilling operation for the stem and it simplifies the forging of the gooseneck. The gooseneck is shaped for forging thereof in a manner such that the meeting of the forging dies does not occur across the top of the stem, and the forging operation can forge identifying insignia on the stem top and/or form a recess of receiving an identification plate. Destruction of the indicia on the plate in the case of a stolen bicycle is easily detected. In order to inhibit commerce in such stolen bicycles the handlebar stem is mounted in the steering column in a manner that requires a special tool to remove it and to replace it by another.
