I have 9 vintage unused linen postcards of scenes in and around the Rio Grande Valley including Brownsville. Alll are clean and in very good condition. Most stamp boxes on the cards have a one cent stamp box, possibly from the 1940's or 50's.
Since the titles can't be seen on the multiple pc views, this is what is printed on them.
