Thank you Ed,
I just came across this in our collection and was trying to decide how to feature it as our next Map of the Month.
Great minds...

Subject: Ports of Entry US Mexico border

Some of you may have heard rumors about recent events at a "border".

In 1979 the United States Geological Survey produced a series of 1:25,000 scale color image maps showing the entire US Mexican border.  There are 205 sheets in the set.

The Library has digitized all of the sheets and high resolution digital files (.tiff, .jpeg, .jpeg2000) may be downloaded at no charge.

Entire set:  https://www.loc.gov/item/87691867/<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.loc.gov_item_87691867_&d=DwMFAg&c=yHlS04HhBraes5BQ9ueu5zKhE7rtNXt_d012z2PA6ws&r=k-oEAmZSZUBvjA0zY3LpLC0r4m8uCY0LyrTxvFxip6U&m=eaygfeg7MduSpF5Ysam4BoxnoynCUbvwCEbmdEWcgEM&s=dVOqJmwz6GCC0yPulajzkFbkKv0lOLoYuL-MRhK6dZA&e=>
