June 14, 1777, the iconic flag of USA was first adopted. Here’s how it has changed throughout the years, including some more interesting constellations than just putting the stars in a rectangle.
The 1837 inverted-star design is a keeper.
Edit: I almost forgot it's called the Great Star flag. Even better.
Very cool Nice graphic!
The Betsy Ross and Cowpens flags are my favorites. I get the idea behind giving every state a star, but 50 stars is way too busy imo
