Thanks Puzzler. I can not take any credit what-so-ever, that would belong to the Disney Pixar animators. Sometime this year I will finally get around to releasing a new Springpatch Local Post stamp themed around Route 66 for its 85th anniversary.
There are multiple images online. Actually, I saved one with all 5 stamps stacked with 2 on top and 3 on the bottom. I then cropped out the other 4 leaving just McQueen and Mater. I am super excited about these stamps, CARS is one of my "new" favorite movies.
I have a Mater diecast car signed by Dean "Crazy Legs" Walker one of the Route 66 inspirations for Mater, a Fillmore signed by his Route 66 inspiration the late artist Bob Waldmire, and a Sheriff signed by his voice actor and Route 66 author Michael Wallis. I have a Sally set aside to have Dawn Welch the owner/cook of the Rock Cafe on Route 66 whom she is based upon to eventually be signed. One day I hope to get Larry the Cable Guy to sign a Mater also. As you can see I'm a bit obsessed, but its all for fun.
