This is a doll jewellery set: a beaded necklace made in the 1930s, a bracelet made in the late 1940s and the same age pendant made in the shape of a lamb.
The child's broach portrays the Scottish business magnate Scrooge McDuck (Uncle Scrooge) licenced by Disney in 1947. This type of broach was popular in the 1940s. The beaded necklace is too small to be worn by child. However a child could have worn the little lamb pendant and bracelet. The bracelet is currently adjusted to a size of a doll hand.
