A few of us discussed this film / musical about a year ago through various emails & PM's. The only thing I managed to find were a few frame captures and we eventually gave up on it. Any further information or a ink would be appreciated. Description below is from the IMDB, but be forewarned; a lot of times the imagination provides a lot more depth than what's actually there:
Helene Töpfer has decided to live with her husband Albert and her son Georg as mannequins in two shop windows of the "Hurtig" department store. While exploring, Georg discovers that all the dolls in the various sales departments once started as living mannequins and gradually transformed into dolls. And they only come back to life for a short time and at certain hours.
