Looking for something 1930-1960. Oldest one I've seen is 1961:

There's also this 1936 (revised to 1940), but it's too small-scale to show any detail in town:

That series probably included a supplemental sheet showing Laredo in more detail, but if so, it's not coming up in my searches.
Trying to figure out whether US 59 (and US 96 before it) were ever signed all the way to the border crossing.
The TSL very annoyingly only scanned the first sheet of any county.

The online preview is only the first sheet, but I think if you download the zip file, that includes all sheets. But unfortunately, the supplemental sheets are not included in that zip file.

Holy crap, you're right. And they're also online: http://www.tsl.texas.gov/arc/maps/images/map4803_page2.jpg
That's a really annoying interface.
