|Francis Hopkinson Flag 1777|
Here are some words for the day from the Francis Hopkinson entry on Wikipedia:
Hopkinson is recognized as the designer of the official "first flag" of the United States. Although he sought compensation from Congress, the letter was somewhat comical. He asked for a quarter cask of wine in payment for the flag, the Great Seal, and various other contributions. Congress used the usual bureaucratic tactics of asking for an itemized bill. After some back and forth, Congress eventually refused on the pretext that Hopkinson was already paid as a public servant. The letter also mentioned that Hopkinson collaborated with others on his designs because he was one of many contributing to the Great Seal. 
While there is no known Hopkinson flag in existence today, we do know from his rough sketch that it had thirteen stars and thirteen stripes. It is believed that his flag used red and white stripes and white stars on a field of blue. Because the original stars used in the Great Seal had six points, we might also assume that Hopkinson's flag intended the use of a 6-pointed star. This is bolstered by his original sketch that showed asterisks with six points.
The legend of Betsy Ross as the designer of the first flag entered into American consciousness about the time of the 1876 centennial celebrations. See Betsy Ross Flag. This flag with its circle of 13 stars came into popular use as a flag commemorating our nation's birth. Many Americans today still cling to the Betsy Ross legend that she designed the flag and most are unaware of Hopkinson's legacy.
It wouldn't be right to have Flag Day without some music so here's a rousing tribute to Old Glory from the 1942 film, Yankee Doodle Dandy. If you don't know this film it's worth viewing as a prime example of wartime propaganda. For the U.S. that year morale was poor on the home front and the battlefield. Any lift in spirit would help sustain our allied fight against the evil infecting Europe and the Pacific at that time. Yankee Doodle Dandy was a patriotic blockbuster.
Sorry about the sound quality and the colorized film. Still works though.
