Waldo is an unassuming bespectacled fellow in a red-and-white striped sweater with matching bobble-hat, with a walking stick and a perpetual smile on his face. He is famous as the star of the "Where's Waldo?" books (known in the UK as "Where's Wally?"), where the reader is challenged to find Waldo in vast, elaborately-drawn crowd scenes. One of the most famous lost people in the world, alongside Carmen Sandiego and Jimmy Hoffa.
