When did the classic Juvenile Magazine StNicholas cease publication it was not despite the title confined to Yuletide?

The magazine ceased publication in l94l. Old Nick packed up the Sack, so to speak.By the way there was a chocolate bar, possibly tied into Yule candy consumption called (Old Nick)-not St.Nick and this was made entirely by automated machinery by the Chunky Candy company and a display plant was visible to all at the Amusement Area of the New York World"s Fair in l965.
