Vintage Italian White Reindeer Collection

My Dad was cleaning out the attic and found these. He did not want any more "junk" and gave them to me. If I had not taken them home that very day, he was going to sell them in a garage sell for $5 each. The beauty alone is priceless. I have always been found of older things; at a time when things were made better.

However, I do not know what these pieces are called. Any further info concerning the time frame, other collection pieces available, or creator would be great. I want to know more about these fascinating reindeer that have found their way into my home just as Christmas arrives.
