At Expo '70 in Osaka, the moon rock in the United States pavilion became one of the fair's most sought-after exhibits. An oral history published by an Osaka Prefecture shopping-district project records a visitor taking his two-year-old daughter in a buggy and waiting one to two hours before finally seeing it. Contemporary reports cited there described waits exceeding four hours, while later first-person recollections also remember three hours in line.
What distinguishes this queue is the disproportion between the wait and the seconds available to inspect a small object brought back from the Moon. A vast achievement in spaceflight was translated at the fair into an intensely physical order: one visitor advancing after another.
