Here is a Marx postwar plastic O gauge toy train accessory, complete with its original box.  It is a #072 Lamp Post in gray plastic and working (as you can see in the first picture).  The box looks complete but several flaps are loose or disconnected (at least it is all here - most Marx comes with no boxes).  The lamppost does have some damage to the base which can best be seen in the last pic.  It is about 6 inches tall and all ready to install on your layout!  Photos show the lamppost and the box from all 6 sides with a yardstick in the shots for size reference.  Priced to sell, with only actual USPS Ground Advantage or Priority Mail shipping charged.
