Astronaut Mickey Mouse is one of a series of pins released in 1998 to commemorate the re-opening of Tomorrowland. The series featured popular Disneyland attractions from the present time and from their past. This is actually a set within a set, as each of the Fab 5 are shown in an astronaut costume (#516), (#518), (#519), (#520) and (#548). Mickey, facing left, has a white and gray space suit with red and yellow trim. His right hand is extended in a "How ya doing?" wave. The silver-finished pin measures 1 1/2" (3.8 cm) tall by 1 1/2" (3.8 cm) wide. The backstamp reads, "DISNEY."
