This is a wholesale lot of 10 sheets of the 4 Stamp Sheet issued by Gibraltar in 2008 commemorating the 50th Anniversary of NASA, featuring the Apollo 11 liftoff, Earthrise from the moon, the Lunar Module leaving the Moon, and the US Flag on the Moon. It's Scott catalog #1157, and is VF mint never hinged. With a 2014 catalog value of $9.75, and a face value of 2.69 pounds Sterling, you're paying just 25% of Scott, and about 58% of face value, which is a great deal for this popular country, and easily retails for 2-3 times your cost.
