This is a beautiful olive green glass oil lamp.  The pattern is a variation of the Eye Winker Thumbprint by the Dalzell, Gilmore and Leighton Company of Findlay, Ohio.  The 'squatty' lamp measures 5 1/2" in height to the top of the font and 14" if you include the clear glass piecrust chimney.  The lamp has a great #1 brass burner stamped "Venus".  The lamp is in excellent condition.
