Here is a VINTAGE 1950's Electric Build-It Set With its  ORIGINAL BOX!

It was made by Jim Prentice Electronic Games of Holyoke Mass 

THE BOX MEASURES ABOUT 3 BY 8 1/4 BY 9 1/2 INCHES

It is new in box, and  was never used. The upper right hand corner of the box top is torn. The is a piece of brown tape on the right hand side of the box top, and some of the design is torn away  from the left hand side of the box top. The box top has a sag in the center, and it has some slight soiling.

Inside, all the components and parts are original and intact, and the instruction manual is in good condition.

I have NOT tested the battery it, to see if it works or not. From its age, it probably is long dead.
