This wonderful 1970 video, using stop-motion animation, tells the story of Santa Claus in a most delightful way.  The story is narrated by Fred Astaire, with character voices by Keenan Wynn and Mickey Rooney.  The music is marvelous and the story is enchanting.  It answers the burning questions we all have about Santa.  Why is he called Kris Kringle?  Why does he wear a red suit and have whiskers?  How did he meet Mrs. Klaus?  How did he come to bring toys to children by going down the chimey and why is his workshop at the North Pole?  What is the origin of Christmas trees and how do reindeer fly?
