This is an original vintage Mexican flag made by Eder Mfg. Co. of Milwaukee, Wisconsin, one of America’s oldest flag manufacturers (founded 1887). Eder used simple red-ink cotton labels like the one on this flag from the 1930s through the early 1950s, before modern woven tags, RN numbers (1959+), and synthetic headers were introduced. The oxidized brass grommets all match their mid-century production style.

This is a large 4×6 ft 100% cotton flag with a construction method that makes it especially rare. The central coat-of-arms was printed on a separate cotton panel and then sewn into a cut-out opening in the middle of the white stripe—a technique used only before the mid-1950s, when manufacturers lacked the ability to print detailed multicolor emblems directly onto large flags. This “insert panel” style is sought after by collectors and is far less common than later one-piece printed flags.

The flag shows honest age, some staining, and normal wear consistent with an authentic 1940s–1950s cotton outdoor flag. A great example of a mid-century U.S.-made Mexican national flag, increasingly hard to find in this size and construction
