Used in late 19th/early 20th Century to place a salve and change it into a vapor to help with breathing, for congestion with colds and allergies. All parts are here and the glass font is stamped with the word Cresolene and Vapo. The milk glass chimney is original and the plated frame is intact with even the tin liner for the salve in the top to be warmed by the lamp. 6 1/2" tall by 3 1/2" wide.
