Flat Stanley's Worldwide Adventures #1: The Mount Rushmore Calamity

Saddle up with Flat Stanley Ever since Stanley was flattened by a bulletin board, every trip is an adventure! The whole Lambchop family is off to see Mount Rushmore. But when Flat Stanley and his brother, Arthur, team up with a scrappy cowgirl named Calamity Jasper, their vacation turns into the Wild West experience of a lifetime. Pretty soon, they find themselves in a real tight spot--even for a flat boy like Stanley! --Kirkus Reviews (starred review)
