Abstract
A two-wheeled hand truck or dolly structure wherein a primary frame is mounted on a pair of wheels and a generally forwardly disposed nose part is connected to project forwardly from the primary frame. The primary frame is made up of side rails connected by cross rails and one of the improvements is concerned with the shape of the side and cross rails which are configured so that they may receive elongate semi-rigid strips bearing information of an advertising or identifying character.
