There are plenty of sites that have information on Norman Rockwell and his paintings. Though I don't know how much information there is out there on this particular painting. Your best bet may be to go to the library and find Norman Rockwell books (try to find a retrospective [complete collection]). You will probably get more information on each illustration in one of those books than you'll find on the Internet. I've included some links to informative websites on Norman Rockwell.
