​​Original vintage magazine ad for APPLETON ELECTRIC COMPANY.  Unilets for every purse, why shop around?  You can get practically anything needed for wiring or lighting in hazardous or non-hazardous areas.  No need to split orders.  Circuit breakers, motors, and starters manufactured.  Main office was located at 1701 Wellington, Chicago, IL.
There is a three inch tear on the left side. This 1959 one page old petroleum industry trade advertisement would display nicely matted and framed.
