A closer look

Imagine spending over a million dollars on a piece of paper only to realize it's rapidly turning to dust. When the rarest surviving movie poster for Fritz Lang's 'Metropolis' was acquired, preservationists couldn't just frame it. They engaged in an agonizingly tedious process called archival linen backing, where the acidic paper was washed in chemical baths to halt decay. Specialists then used high-powered microscopes and tiny tweezers to manually align individual paper fibers across decades-old fold lines, effectively reweaving the paper matrix at a microscopic level so the restoration was completely invisible to the naked eye.
