Tiny Tim was a comic strip created by Stanley Link, about a small boy named Tim and his sister Dotty, who were only two inches tall. The strip ran from 1933 to 1958, and over the course of the strip the brother and sister grew to eight inches tall, then to normal child size, then back to two inches tall, and then gained the ability to switch back and forth between two inches and normal child size. They had many adventures in the tiny world over the course of the strip's run, and gained some animal friends along the way, including the bird, Paddy, who you see in the final panel.

This particular strip is interesting, because I'd never thought about Santa Claus preparing for Christmas Eve in this way. I thought the myth was that Santa could use his magic to shrink to the right size so he could fit in any chimney, or whatever opening was available to him, so he didn't need to worry about fitting in anywhere. In fact, it seems like that story would fit quite well in a comic strip about tiny people. Of course, Dotty could just have been dreaming...
