Thank you for sharing! The little mouse that saved Lionel from going broke in 1932, or so the story goes. The late Ron Hollander in his book All Aboard! said that Lionel sold some 250,000 of the Mickey and Minnie Mouse hand cars, and maybe could have sold 100,000 more if they had the time to manufacture them before Christmas 1934. Ron noted that at a $1 retail price, Lionel probably sold them for $0.60 to the retailers, so not much profit, but it did put Lionel in the news and helped sell other, higher priced items.
Having seen this video, I can see why they were so popular 90 years ago.
