Chapman Floral Leaded Lamp (Attr.)

18.5" diameter shade consists of granite backed and regular glass arranged with a white floral pattern apron against a two-toned green petal background. The shade rests on a wonderful 2-socket "gooseneck" base with embossed base. Base is solid bronze (and not copper plated pot metal which most were), and has a prominent HANDEL tag leaded into the underside. The base stands an impressive 25" tall.

Ed. Another characteristic of Chapman shades is heavy leading, like on this shade.
Not all have this, but enough do that it can be a clue in attribution.
