High in the sky on the Fourth of July

Okay, we all know the Declaration of Independence wasn't signed on July 4, 1776. That is, however, the date it bears as "An Action of the Continental Congress."

But did you know that the first and second drafts of the Declaration of Independence were on hemp paper (made from Cannabis sativa, still mostly illegal in the United States) and the final one on parchment (animal hide)?

Raise the flag high on this Fourth of July!
