Collector DOLL,VINTAGE ,VERY RARE. GIRL WITH TEDDY BEAR.

Very rare doll holding teddy bear while wearing robe and house slippers. She holds a book with swan on it and teddy bear. She's blonde with blue eyes. It's signed with #901. She's heavy at 2 3/4 pounds. She has a felt bottom. I can't tell what she's made of..I haven't cleaned her other than dusting due to her value. I've had her for several yrs as I purchased her due to her value.
