This is very nice No. 1 size sweet heart lamp with a green font and clear base. The lamp measures 8 1/2" in height to the top of the font by 4 7/8" in diameter at the base and was made by the Dalzell, Gilmore and Leighton Company of Findlay, Ohio.  The lamp is in excellent condition with  a minor flake on the bottom of the underneath side of the base and a brass Banner burner.
