The Pop! Vinyl figure of Eleven, numbered 1457, from "Stranger Things" likely represents a specific moment, outfit, or season portrayal of the character, given the extensive range of Eleven figures produced to capture her evolution throughout the series. While I don't have the specifics of each figure's release details as of my last update, this particular number suggests a newer addition to the Funko Pop! line, possibly tied to the latest seasons of "Stranger Things."

Characterised by her psychic abilities and a deep, evolving storyline, Eleven has been depicted in various costumes and scenes in Funko Pop! form, ranging from her initial appearance with a buzzcut and hospital gown to later seasons featuring more developed personal style and growth.
