Vintage Nina Ballerina Like Doll 19" 1955 Vintage with Original Ballet

I believe this is a 1955 Nina Ballerina doll.  She has a vinyl head with a hard plastic body.  She stands on her pointed toes, like a ballerina. She has blue sleep eyes with good molded lashes.  She's about 19" tall.  She may have been sold through Sears catalogue. She has nice hair and is in good shape for her age. I do not  think this doll was made to sit down. Thanks for looking. Shipped via USPS.
