at the Atlanta airport, Nutt’s “Flying Vegetable” series, the design was inspired by jetliners. This humorous work was hand-carved by Nutt from wood and painted to capture the details of this indigenous American crop.

 

To accompany the flying corn, Nutt created an air traffic control tower. 

Would the right pun be "earplane" or "cornair"?

Nothing is more appropriate to guide the “Corncorde” on its journey than a air traffic control tower composed of a giant carrot and motorized spinning butter bean also made out of carved and painted wood. “
