Turns out you can buy surplus CTA signs from the Illinois Railway Museum so I got a Blue Line carcard map, a full L map, and a Western Blue Line station sign
not affiliated with them, I just think this is super cool. it took like 6 weeks to get them but it was worth it
ETA because I got a couple DMs about it: the stuff is on https://www4.irm.org/irmsigns/ but you have to fill out a paper form, the online cart is broken
