This Thirstee Walker doll has T211 on the back of her head and what looks like a number 19 even though she's more like 20" tall.  She has Horsman Dolls imprinted on her back.  Based on this model number she appears to be a 1969 walking version of the Horman Thirstee Baby doll.  She has an adorable face with bright blue eyes, and it looks like original factory style hair.  Surprisingly good condition given that she is an out of box doll, she was taken care of very well.  I could not find any pictures of this doll dressed or in this good condition but based on coloring and style I would say this was her original outfit as it's appropriate for the time period and with other versions of this doll.  She has sleepy eyes that open and close and hands that can grasp a wide bottle (thin ones that are about 1" thick do not work it needs to be a 2" or 3" wide bottle).  She has an drain hole at the back in case she is fed "real water" and a hole at the mouth.  She has her original vinyl/plastic white shoes and she has been cleaned.  Her underwear appears original but I would describe them in as is condition as they look very old but are still hanging on.  No staining.
