Authentic Vintage 1960s Blue and Green Pumps with Bows on Toes

These are absolutely beautiful authentic vintage pumps from “palizzio” with the marking “21*” in the heel. There is some kind of signature or marking on the inside of the heel back and another on the bottom of the left toe, as pictured. These are definitely used but in excellent shape. An incredible find that are just barely too small for me. Size is not marked but my best guess is a narrow 7. Heels are 3” high, shoes have roughly 9” of space for a foot. Happy to answer additional questions or share more details.
