The system and method of the present invention includes an upper frame
mounted on a support structure, such as a truck, building, or billboard,
three adjustable frame assemblies mounted on the support structure below
the upper frame, and sheet material having an upper sheet tab inserted
into the upper frame and lower, right, and left sheet tabs inserted into
the adjustable frame assemblies. The frame assemblies can be adjusted to
vary the tension in the sheet material between the upper frame and the
adjustable frame assemblies. The method includes the steps of inserting
the upper sheet tab into the upper frame, inserting the right, left, and
lower sheet tabs into the adjustable frame assemblies, and adjusting the
adjustable frame assemblies so that the sheet material is pulled taut
between the upper frame and the adjustable frame assemblies.
