1950's Madame Alexander-Kins Straight Leg Walker Doll 7.5" Tagged Pink Checkered

Madame Alexander-kins Pink Checkered Play Set
Description Up for auction is a beautiful early 1950's Madame Alexander-kins 7.5" (19 cm.) all hard plastic doll, Wendy face mold. Marked ALEX on her back. She has a socket head,five piece body with walking style legs,colored eyes and blonde hair. She is wearing what I believe to be her original outfit: pink and white checkered play suit with lace trim, matching sunbonnet with wide brim, matching gathered skirt, socks, black velvet side-snap shoes. The costume is tagged Alexander-Kins.
Condition :Cosmetic condition is excellent. Face paint is perfect. Her outfit is very clean, no stains or tears. No bad odors. Only issue I see is a small black dot-sized mark on her left leg (see picture #12). Her walker mechanism isn't working properly. Her legs are a bit loose. I move her legs and her head turns slightly. Her arms might need restringing as they are loose and don't hold a pose.
Please ask any questions before bidding. Thank you for looking.
