Arrco likely produced ballerina-themed playing cards for commercial appeal, as the images on these cards, such as a "fan dancer," were designed to be attractive and popular, especially during the mid-20th century when such themes were common for entertainment and consumer goods, as seen in other Arrco "pin-up" or themed decks. 

Arrco, established in 1927, was known for its innovative plastic coating on decks, making them popular and easy to handle. The production of visually appealing, specialized decks aligns with the company's innovative and quality-focused approach to playing card manufacturing. 

Comes as is.
