This Official First Day Cover bears the 9¢ and 13¢ "Right of the People Peaceably to Assemble" stamps issued March 11, 1977, in New York, NY. The se-tenant pair comes from the Vignettes of Americana booklet and is tied by a crisp "First Day of Issue" cancel.
The stamps commemorate the First Amendment guarantee of peaceful assembly, pairing a classic view of the U.S. Capitol with the Stars and Stripes. Their release marked an important philatelic milestone: the first time the U.S. Post Office placed stamps of two different denominations in a single booklet pane.
The cachet reproduces a handsome oval vignette of the Capitol and notes the booklet's convenience for the public. No addressee appears on the cover.
A clean, well-centered example that makes an excellent addition to any Americana, First Amendment, or modern booklet-stamp collection.
