On this Constitution Day we wanted to recognize the fascinating science behind preserving one of America's greatest documents. Constitution Day is celebrated every September 17 to recognize the signing of the United States Constitution.
"Constitution Day commemorates the formation and signing of the U.S. Constitution by thirty-nine brave men on September 17, 1787, recognizing all who, are born in the U.S. or by naturalization, have become citizens." -- www.constitutionday.com
