E Bay makes looking for these fun little snow babies easy.  Just like anything else, you need to educate yourself.  Unknown to a lot of people, is the fact that the old molds have been used again and again particularly in the past 5 years.  Best way to educate yourself is to get Big Book of Snow Babies by Mary Morrison and Snow Babies, Santa and Elves, Schiffman publication.

If the snow baby you are looking to buy is not in either of those books, or it looks the same but different, beware..it is probably a recent reproduction.

Happy hunting.
