Pop-up Collectible Birthday Cards for Display. One has Tow Mater and Lightning McQueen on it from the Cars Movie. Lightning McQueen pops up as he jumps off a ramp when you open it. Another is a complete Amusement Park that folds out and stands up with colorful rides in it. Another is an Archeology Joke as they dig up "Your Birth Certificate." These are used cards with sender's greetings an signatures on them.
