Abstract: A portable platform has a first configuration where it may be transported safely over public highways and a second configuration where it is transformed into a display that attracts crowds of visitors at a fair or festival. The platform is elevated above a support surface by a conventional wheel and axle assembly, and is accessible when in its display mode by a stairway. A large structure positioned at one end of the platform is shaped like a beverage bottle, to be promoted and has a hollow interior to house equipment and workers. A door formed in the structure admits personnel, and a window enables the serving of the product being promoted to patrons attracted to the platform by the large structure. Safety rails and a tent-like covering complete the assembly.
