2011 Mayreau 9/11 10th Anniversary Souvenir Sheet

This souvenir sheet was issued by Mayreau, part of the Grenadines of St. Vincent, to mark the tenth anniversary of the September 11, 2001 terrorist attacks, bringing together four stamps depicting different memorials and tributes connected to that day. The sheet includes stamps showing the Tribute in Light memorial recreating the fallen towers with beams of light, the completed National September 11 Memorial in New York, the Flight 93 National Memorial in Pennsylvania, and a photograph of President Barack Obama attending a memorial service at the Pentagon. Together, the four images span all three attack sites and reflect how memorialization efforts had progressed in the decade following the attacks.

The sheet's design places its four stamps against a nighttime photograph of the Brooklyn Bridge and Lower Manhattan skyline, illuminated by the Tribute in Light beams rising in the background. Its heading, "In Memoriam," paired with "10 Years, Never Forget," reflects the language commonly used across memorial observances held throughout the United States on the anniversary itself. Mayreau, a small island within the Grenadines of St. Vincent, joined numerous countries around the world in issuing anniversary tributes, reflecting the global scale of mourning and remembrance the attacks continued to generate a full decade later.
