A billboard sign includes abutting rectangular tubular sections forming a frame using a rectangular tube extending across abutting ends within the tubular sections. The rectangular tube is biased against adjacent inside wall surfaces of the tubular sections for securing and aligning the tubular sections to each other. Risers extend between opposing horizontal frame sections and define a flat riser plane. Stringers are attached to support posts and define a vertically oriented plane. With risers defining the flat riser plane, the stringers horizontally attached to support posts and aligned for defining a vertically oriented plane, the flat riser plane can be aligned with the vertically oriented plane for securing the frame to the support posts in a flat plane of the frame vertically oriented as desired, regardless of the orientation of the support posts. A flexible substrate may be extended across a periphery of the frame with a message carrying surface.
