Could have sworn I posted in here a couple of years ago, but apparently it's gone. Oh well.
I got this on my last visit to NYC in 2003. As of a couple of years ago, this car was still in service, but I don't remember what it was renumbered to and thus can't tell if it's still active or not.
This came from Chicago - it was a bit of a trip to find the CTA "gift shop" but ended up being well worth it. This sign is in amazing shape - near-mint, I'd say - and was around $35. All-metal with very sharp edges!
I think I have a few maps from defunct SORTA/TANK routes lying around as well...don't know where they are off hand.
