Emeralite Articulated Brass Bankers Lamp

^{An Amercian Emeralite Brass Bankers Lamp, the overlaid glass, shade is green on the outside and white on the inside giving a lovely glow - apparently to aid concentration!  The brass frame is articulated at the top to adjust the angle of the shade and at the bottom of the support above the square shaped base which is weighted internally.}   The back of the shade has the remains of it's 'Emeralite' paper label.
