Astronaut Pluto 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). Pluto, facing right, wears a white and grey with gold and green trim space suit. His front paws are extended and he grins with his tongue hanging partly out. This silver-finished pin measures 1 9/16" (3.9 cm) wide by 1" (2.5 cm) tall. The backstamp reads, "DISNEY."
