    This poster is currently unbacked. At check out, you will be given the opportunity to add backing which would cost $125 and take approximately 4 weeks.

    Linen backing is the industry standard of conservation. Canvas is stretchered and a sheet of acid free barrier paper is laid down. The poster is then pasted to the acid free paper using an acid free paste. This process is fully reversible and give support to the poster. A border of linen is left around the poster and can be used by a framer to mount the poster so that nothing touches the poster itself. Backing is what we recommend for framing, and for any poster needing restoration.
