From Wikipedia:

The Gazette of the United States was an early American partisan newspaper first issued on April 15, 1789, as a biweekly publication friendly to the administration of George Washington, and to the policies and members of the emerging Federalist Party. The Gazette was originally published in New York City by editor John Fenno, but followed the United States Government in 1790 to its new temporary seat and capital in Philadelphia, Pennsylvania.

This issue contains an act of congress signed in print by George Washington as President, as well as a letter from Louis XVI of France to the mayor of Paris (this was 3 months before he was deposed and 8 months prior to his execution on the guillotine.)
