1987 U.S. Constitution Bicentennial First Day Cover Washington Elected President

Got this U.S. Constitution Bicentennial First Day Cover from 1987. It features the 'Washington Elected President of Convention' artwork and has the May 25, 1987 Philadelphia postmark. It's in a protective sleeve and looks pretty clean for its age. Cool little piece of history if you're into stamp collecting or just like old Americana stuff.
