Hamburg – “Who? How? What? Why? Why? Why? If you don’t ask, you’re stupid!” The children’s show “Sesame Street” has been starting with this well-known song for decades. The German-language cult show with Ernie and Bert, Elmo and the cookie monster has been around for 50 years. Now a large special exhibition is to be dedicated to her in Hamburg. The Museum of Arts and Crafts wants to lure its visitors into the world of entertaining dolls on around 700 square meters.
