The sculptures are of the Apollo 11 moon crew – Neil Armstrong, Buzz Aldrin and Michael Collins – as well as a separate buttery interpretation of Armstrong in his spacesuit by the lunar module, Eagle. There's also a butter cow and calf standing beside the Apollo 11 patch. This took more than 2,200 pounds (1,000 kilograms) of butter to create.
"Those who remember the moon landing often recall exactly where they were and how they felt, and the 50th anniversary is the perfect time to pay tribute to this amazing event and share that excitement with a new generation," said Jenny Hubble, senior vice president of communications for the American Dairy Association Mideast, in a statement.
She added that the sculpture pays special tribute to Armstrong, who is originally from Wapakoneta, Ohio. "Ohio also has a special connection to that day, as one of our own took the first-ever steps on the surface of the moon," Hubble said.
The butter display is expected to attract 500,000 fairgoers to the Dairy Products Building, where they can also learn about Ohio's role in the dairy industry. In between gazing at the yellow sculptures of the crew, visitors will have a choice of many dairy foods, including ice cream, milkshakes, cheese sandwiches — and of course, milk.
