Did your press have a personal beef with 1920s poetry or something? That's a brutal fail, but honestly, steaming the pages back is next level save. I would have just stared at the crushed mess and cried. Total props for not giving up and getting the linen tape out. Makes my DIY projects look like a toddler's craft time.
Did anyone check if the paper itself was acidic and just gave up under pressure? @emmahayes, that steaming trick was smart because heat can relax the fibers. Honestly, saving old paper is a whole science most people don't even think about.
