This is a nice advertising pocket mirror marked "A Hot Time At Any Time If You Use The Gilt Edge Furnaces & Boilers - R. J. Schwab & Sons Co. - Exclusive Manufacturers - Office 283 Clinton Street - Milwaukee, Wis. - Gilt Edge Assures Comfort and Economy".  The pocket mirror measures 2 3/4" in height by 1 3/4" across with very nice detail.  The mirror is also marked on the edge "The Whitehead & Hoag Co. , Newark, N. J.".  The back of the mirror is in very good condition with a discoloration spot - the mirror shows some minor wear.  A great advertising pocket mirror.
