Photocopy a few dozen sheets of paper or scan it for display use. Then get a thick plastic sheet protective cover to put the BS sheet in and store it flat in the dark.
I scanned my broadcast sheet and window sticker. I then laminated the scanned copies and used them during car shows. Originals were placed in plastic sheets and stored.
I put my original in a clear vinyl sleeve (sheet protectors) and store it in a fireproof lock box with the titles and other important documents. I made copies and put those in a notebook that I can share with others.
I do some archival work with old documents. Look up "archival quality storage supplies". Normal paper and plastic folders and bags off gas chemicals that will eventually destroy the paper and the inks.
I had mine for about 5 minutes. Completely disintegrated. I wish I would have first left it in the seat springs, then sprayed it with aerosol clear and then dealt with it from there.
