Astronaut Donald Duck 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). Donald, facing right, sports a white and gray space suit with blue and yellow trim. Both arms are in the air and he is smiling. This silver-finished pin measures 1 9/16" (3.9 cm) wide and 1 1/4" (3.2 cm) tall. The backstamp reads, "DISNEY."
