This is a vintage Ceramic Light Up Christmas Tree by Atlantic Mold from 1974. It is 20 inches tall and 16 inches at the widest point. There is a base which you can take the main portion off and there is a socket for a lightbulb. The power cord has a switch on it to turn off and on.There are dozens of light pegs that make up the colored lights in the pictures but I have ordered a replacement set with 50 lights which will be included. This unit is in very good condition and working order. As pictured, it has two chips. One at the top where the topper goes and I have that pieces which can be glued on and there a tip of one of the branches which can easily be covered by touchup paint or other method.
There are 14 or 15 of the lights missing but I suggest ordering a batch to have on hand as some of them come out easily so you are bound to lose some others.
