Event covers are decorated, stamped and canceled commemorative envelopes. They are created to celebrate an event or note an anniversary. It explains what is being commemorated on what date, and generally also includes an illustration page.
Ideally, the stamps used relate to the celebration (for instance, space stamps for a shuttle launch). Cancels are either obtained in the city of the event (such as Kitty Hawk for the Wright Brothers first flight anniversary) or, for larger quantities of envelopes, from a special cancellation unit maintained by the Postal Service in Kansas City, Missouri. If a special cancellation (one with a design) has been created for the event, you can generally only receive that cancel from the local post office.
Following is the event cover and it has Gandhi stamp from USA. This commemorative event cover has postal cancelled on March 9 1961 on Polaris Missile Fired at 1pm from Cape Canaveral FLorida with cancel from Patrick Air Force Base near Cape Canaveral in Florida.
In this cover the main important thing to notice is
1) Event. (What is event?)
2) Place of cancellation (From where missile was fired. )
3) Date of cancellation ( Date when event occured.)
4) Stamp on cover (what stamp should be on cover to make it more important).
This cover was not made specially for Gandhi philatelic collection. It was made to celebrate Polaris missile launch so this makes some what important for Gandhi philatelic collection because it was not made with Gandhi in mind. Also this cover don't justify Gandhi's Non-Violence principle which he follows throughout his life so this Missile launching does not go with this stamp.!!!!

It was designed to be used as part of the Navy's contribution to the United States arsenal of nuclear weapons, replacing the Regulus cruise missile.
