According to John Patrick's play The Strange Mrs. Sevage.

A very rich man's widow loves charity. She believes that the money she received should serve other people as well. Therefore, she promises to spend a lot of money to fill the city with artificial snow on New Year's holidays. After all, this has become a real problem for children - the lack of snow in recent years. Toddlers suffer that only on television can see a true white-tale. But the deceased husband's adult children do not share the stepmother's thoughts. They want to take all the money for themselves. They send away from the city Olga Nikolaevna and start scouring everywhere in search of securities.
