"In 2004 the USPS issued this stamp honoring the fiftieth anniversary of the founding of the U.S. Air Force Academy, located near Colorado Springs, Colorado. After the U.S. Air Force was separated from the Army in 1947, Congress authorized the establishment of a school to train Air Force officers. A coded image of a falcon below the denomination is visible when viewed through a U.S.P.S. Stamp Decoder lens."

☒ 411 on PLATE BLOCKS
"In philately, a block is a group of four or more unseparated stamps. Blocks are of interest not only because they are rarer than individual stamps, but they also preserve relative positions of stamps as they were originally printed, information that is crucial to understanding how the stamps were produced.
The most commonly collected kind of block is the plate block, which includes the part of the margin where the serial numbers of the printing plates may be found."

ESPECIALLY GREAT FOR COLLECTOR OR U.S. AIR FORCE SERVICE PERSON.
