Maps for sale or trade

[US71]

Dang...thinking I donated a bunch of maps somewhere...but I might still have them somewhere.  I'm looking for old Texas/Austin maps.

How old? I may have a few.

New map want:

I may be looking to replace a part of my collection of NYSDOT maps, specifically the Urban Areas atlas that was issued in 2000 as a supplement to the NYS Atlas & Gazetteer of 1998. I'd consider buying the whole atlas if available, but I specifically need the supplement. My dog ate it.

I don't know whether anybody would have a copy for sale or trade, but maybe there are some map dealers you know of who'd specialize in rare, out-of-print, but not antique, maps like this.
