Hi. I recently purchased a 1940s/1950s Mary Hoyer doll in her original case. Inside the case I found the red rubber bathing cap with its detachable strap that goes to "Jo-Ann's Swimming Suit". This item is in pristine condition. I know this cap is a rare accessory. (especially in this condition). I would like to list the cap but I have no idea of the value. Can anyone help? Thank you.
