Abstract: A portable holder for transporting rolled-up blueprints or other materials. The holder is comprised of at least two elongated hollow tubes fixed together at their ends by front and rear headers. A carrying handle is fixed to one of the tubes to allow a person to easily lift and transport the holder in one hand. The front header is provided with openings aligned with the hollow interior of each tube to allow materials to be inserted into or removed therefrom. The front header may be provided with hinged doors which are secured in the closed position to insure the integrity of the materials within the tubes.Each of the headers may also be provided with projecting fingers and aligned holes on opposite side edges to enable a number of portable holders to be stacked together and held in place by the coaction of mating fingers and holes of adjacent portable holders.
