If you are a serious flag collector or if you plan on displaying your flag outdoors, you should consider our line of Nylon flags. Our Alamoflags are made of 100% Nylon, finished with canvas headings and brass grommets, primarily for outdoor use. Nylon flags are heavier than Polyester and stand up well to sun exposure. A Nylon flag provides a longer life of service and enjoyment. MADE IN THE USA! The Mexican constitution of 1824 gave the people of Texas rights similar to those enjoyed at the time by the citizens of the United States, but every new Mexican government attempted to increase control over Texas. To call attention to this, Texans removed the coat of arms from the center of a Mexican flag, and replaced it with the date of the constitution. It was this banner that flew from the walls of the Alamo.
