Mater Private Eye at Junkyard Jamboree
Below the window, notice the intentional misspelling of "Lightyear Tires." I'd originally thought it represented the way Mater would misspell it in his imagination, but mwh1980 reminded me in the comments that these are the counterfeit tires Mater was investigating.
It's a fantasy world (Mater's recollections) within a fantasy world (Radiator Springs) within a fantasy world (DCA)!
