Antique Chicago Worlds Fair Mirror??

Very excited to list this Antique "Chicago" Small Hand Held Silver Plated Mirror. I have only been able to find a few of these online and they are saying this is from the Worlds Fair in Chicago. The mirror is 4" in length and the round mirror area measures 2". The mirror is in good condition for the age, some of the silver plate appears to be rubbing off in areas. The mirror loos pretty good, I don't see and chips or cracks.
