This is a very unusual antique miniature kerosene lamp in white milk glass with embossed design and a decorated metal brass wall hanging mount.  The lamp measures 2 1/2" in height to the top of the font and 7" in height if you include the clear glass chimney.  The brass hanging bracket has some nice decoration and measures 3 3/4" in height - could be used to hang on a hook or to carry.   A very similar pattern is pictured in the Smith - Miniature Lamps I Book on page 56 Fig. 56.  Condition is excellent with minor wear to the metal fingerhold.
