Abstract: The invention comprises a shipping container with a flexibly mounted adjustable, removable suspension system for transporting works of art of various dimensions. The container includes two identical composite wall sections, each section having a flanged mating surface to form a seal when the container is closed. Each of the wall sections is a composite structure having an inner and an outer skin with an insulation layer in between. Each composite wall section is flexibly mounted to an outer flange to further cushion the assembled shipping container for mechanical shocks. Longitudinal and latitudinal stiffeners are attached on each end to the second flange and span the outer surface of the container. The adjustable, removable suspension system within the container includes a support frame resiliently mounted in each composite wall section. A support strap system in combination with abutment angles support the framed work of art and fix its position relative to the frame.
