Philips Spotline Promotional pencil pot

Given to me for free in a lighting shop. They probably got this around 1989? with a bulk purchase of Philips Spotline reflector lamps as they had just introduced the more bulged reflector shape and were keen to advertise it in that year I think. Anyway, the box is pretty much a direct copy of the actual lamp boxes, just slightly larger and made of plastic/card and covered with a transparent plastic foil material.
