A follow up from @jrodrigues39.bsky.social on his batter aging curves, looking at what they tell us about free agent hitters. Schwarber forced us to redo all the scaling (on the right is the original plot)

Chicago people, looking for guidance: I have a couple very old newspaper pages from early 1900s I would like to preserve & get framed.

Anyone know of a place in Chicago that can do that? I know a special coating has to be put on newsprint to avoid further degradation & am struggling to find a place
