Wood ? Base Only!  A couple of nicks out of it.that would be very easily touched up.   3 fork shade bracket measuring 8.5". The dome you choose should be bigger that that so that these arms would prop up the shade with stability.  I would go with at least 12".  NO shade OR BULB  included.  I did include pics of ideas.    Small socket in the middle for a little light bulb.  Original vintage piece that has original wiring.  The brown cord is 8 feet with a dial control.   Finish off this piece with your imagination!  Razor coral was used originally., but there are many possibilites. Foam rubber toadstool, resin, glass and shell etc. or even crystal balls.   4 stumps of varying heights.  Would look even better if the moss was freshened up.

Burl wood, shiny shellac.measures 16"longx14.5"widex10.5" high.  The height would naturally increase with your type of shade.

Works! Made by Wizart Canada 1986.  Heavy.  ***Disclaimer...there is a possibility this is resin.
