What’s in the suitcase?

Dolly is the treasure in the battered suitcase.
She’s lived in that suitcase for as long as I can remember and probably much longer. I remember my mum complaining that she’d not been allowed to play with her when she was a child because grandma was convinced she was valuable (the doll, not my mum!). Now I’ve looked at her more closely, she’s clearly been played with by someone as there is paint damage around her joints and to her hands.
