Tin advertising sign for 'Storm & Lemercinier', a company that specialized in closing gates and agricultural machinery. 
 
The sign was manufactured in 1951 by Rob Otten (Brussels), a company well known among collectors of publicity material. It has a beautiful, convex edge and the letters are also embossed.
 
Considering its age, the plate is in (very) beautiful condition; hardly any scratches or rust. The 4 suspension eyes are also still intact.
