Howdy Doody himself is a freckle-faced boy marionette with 48 freckles, one for each state of the union (up until January 3, 1959, when Alaska was admitted as the 49th state), and was originally voiced by Buffalo Bob Smith.[6] The Howdy Doody show's various marionettes were created and built by puppeteers Velma Wayne Dawson, Scott Brinker (the show's prop man) and Rufus Rose throughout the show's run.[7] The redheaded Howdy marionette on the original show was operated with 11 strings: two heads, one mouth, one eye, two shoulders, one back, two hands and two knees. Three strings were added when the show returned—two elbows and one nose.
