First sheet music publication of The Star Spangled Banner.

"The Star-Spangled Banner" is the national anthem of the United
States. The lyrics come from the "Defence of Fort M’Henry", a
poem written by American lawyer Francis Scott Key on September
14, 1814, after he witnessed the bombardment of Fort McHenry by
the British Royal Navy during the Battle of Baltimore in the War of
1812. Key was inspired by the large U.S. flag, with 15 stars and 15 stripes, known as the Star-Spangled Banner, flying triumphantly
above the fort after the battle.

The 15-star, 15-stripe "Star-Spangled Banner" that inspired
the poem.
