In cooperation with Space Coast Cover Service, we are pleased to offer collectors and the public event covers commemorating the launch and landing of STS-121 / Discovery.A "cover" is an envelope canceled at the location and on the date of a milestone event. Our STS-121 covers carry the Kennedy Space Center postmark.Three different cover configurations are available: Launch date only; Landing date only; and a double cancellation with both Launch and Landing. (Note that the illustration to the left is only a mock-up and the final cover differs in appearance, including stamp choice.)TOS double canclled
