An antique/vintage hand mirror by the American company INTERNATIONAL SILVER. The pattern I think would date it to roughly the 1920s.  The glass is firm in the mirror.  There is some light minor denting of the silver as you would expect for the age and a few dark marks.  This is approx'y 33.5cm long and the diameter of the mirror and surround is approx'y 11cm at widest part. .  Please zoom into all photographs as part of description.
