Linus and Snoopy are entering the theater where the Spelling Bee is held from the interior of the building. When Linus tells the usher he's a friend of one of the contestants, they are shown going inside from the exterior.
Charlie Brown is seen setting off for the spelling bee with a suitcase and a duffel bag. Upon arrival, he only has the suitcase. Upon return, the duffel bag reappears, but when he gets home, it's only the suitcase again.
