Around Halloween you can find slightly similar craft items, made from Indian maize, for sale in supermarkets, like this...
I'm not sure how those are intended to be used. They may be intended to bring good luck, or to be a charm of some form. Or they may have been used in some form of ritual. Corn has a religious significance in many cultures (including Christianity).

You could make some very original Christmas decorations.
Be careful where you leave them, because mice love them.
