Great vintage find! This mirror was produced in 1960s when the plastic happened to be a new and rare material, very promoted for the use in homes. The things for personal use started to be made from plastic and this mirror is a great example of that. It is in a square shape with a lovely detail on the frame, very much in the mid-century modern style. The mirror can be hang in a square shape or rhombus style, it is prepared for both by the manufacturer.
Great vintage condition. Original mirror piece. The plastic shows some minor age patina.
