Chartered in 1982 and based in Baltimore, Maryland, the mission of The American Flag Foundation is "to encourage Patriotism in children and adults, achieved through our education and outreach programs, focused on the American Flag."
Over 100 volunteers at AFF work with school systems, all levels of government and other organizations to provide educational opportunities to understand the history and origins of the flag. Resources for teachers can be found here.
For example, did you know the original flag with 13 stars and 13 stripes was adopted as the national flag in on June 14, 1777, but it was another hundred years before the first national observance of Flag Day in 1877? It wasn't until 1949 that the holiday was made permanent by a Congressional resolution.
If you have questions about flag ettiequte and Public Law 829, aka "The Flag Code" you'll find answers in this pamphlet. Some facts I found interesting... DO raise it briskly and lower it slowly and ceremoniously, DON'T use it for any advertising purpose, on anything intended to be discarded after temporary use or as part of a costume. So much for that parade.
There is a rather dramatic reading of the Star Spangled Banner origin story at this link and, if all of this information has inspired you to buy an American flag (or a state flag or the flag of another country), you can do that here. No social media links for The American Flag Foundation, though you can always make a donation to support their work.
Have a wonderful, socially distanced, 4th of July!
