Anyone know approximate value of 1964 Worlds Fair Walt Disney "It's A Small World" Christmas Ornaments?

I have a set of 1964 Walt Disney "It's A Small World" Christmas ornaments that were purchased by my in-laws at the 1964 Worlds Fair on their honeymoon. It was the first time to my knowledge "It's A Small World" was revealed to the public. It is a complete set in the original box featuring several of the "Small World" characters in authentic clothing. I am curious to know If anyone has seen another set, or knows a value of this set. Thanks in advance for your time. :)
