This pair of flats date to the middle of the 1860's, when shoes built with a right and left last became popular.
They are made out of brown velvet and patent leather tips. The velvet has very faint designs of flowers and butterflies painted on it in orange and green paint. The patent leather now lost its "patent".
These would have been worn as house slippers, perhaps by an older lady who liked the, out of fashion, flat slippers of her youth. Completely hand sewn and lined in white cotton. They measure 11" long and 3" wide, a ladies size US 10/UK 8.
