I picked this ornament up at the Columbus Flea Market for $5
Air Mater is a "Car Toons: Mater's Tall Tales" short released in 2011, and can be found on the "Cars 2" DVD or Blu Ray, the Pixar Short Films Collection 2 DVD or Blu Ray, and iTunes, which is where I purchased it.
Back to the ornament!
And here is the back of the box.
"Mayday! Mater bites off more than he can chew when he takes off with a crew of stunt planes in the animated short Air Mater. He wants to be part of the aerial action, but this is a little too much excitement! But never fear-Lightning McQueen is just a loop-the-loop away and wouldn't dream of letting Mater down."
Great detail in this ornament.
The propeller turns!
This short introduces Propwash Junction, a town inhabited by planes, featured in the animated movie... Planes.
