Lynne Marie Stewart, who was the most beautiful woman in Puppetland as Miss Yvonne on 'Pee-Wee's Playhouse,' has died at 78.

Very sad.........

A sad day for fans of Pee-Wee's Playhouse with the passing of Lynne Marie Stewart who played Miss Yvonne for the show's entire run. I remember Mr. Window's intro "Hey Pee-Wee. Here comes the most beautiful woman in Puppetland." May she rest in piece.
