Titteliture

Titteliture was the Sveriges Television's Christmas calendar and Sveriges Radio's Christmas Calendar in 1960. The radio version was called Barnens adventskalender ("The Children's Christmas Calendar").
Plot.
Every time, except for Wednesdays (that were TV-broadcasting-free in Sweden at that time), a "tomte" called Titteliture (a name created from "tittut", the Swedish term for "peekaboo") opens a calendar window. Behind each calendar window is a guest, and adventure or a riddle.
