The same gold tone bracelet was also sold at Disneyland. It's attached to a colorful aqua-blue card inside a gold-colored metal box with a clear plastic lid. Dates from 1966. Bottom center of card reads, "© Walt Disney Productions MCMLXVI." The Prince is pictured to the left, Snow White on the right.

This example also dates from 1966 but has a slightly different chain design. The characters appear to be more silver tone rather than gold.

Another Disneyland issue. Not dated but probably circa 1960s. From the "Little Miss" line.
A "© Walt Disney Productions" imprint is seen on the back of Snow White.
