Mid Century Rare Elephant factory family chained together

Product code: Mid Century Rare Elephant factory family chained together
Rare find! I heard that during the 50's the factory headboards or book stands and people started collecting these animal families and put them on the headboards. The large elephant is 5 1-2” tall. The small elephants are 2” tall. There is some color loss on them. There are no cracks or chips. Great vintage condition except for small amounts of color loss. They are adorable!.
