The Art Deco metal plaque above the door is worth a look.
Barely noticeable between the door and the metal shutter is another ghost sign. It says simply "Billar" ("Billiards") and was painted most certainly after the ironmonger's closed down. Was this a workshop where they made billiard tables, or simply a place where people could come and play? With the shutter closed, I couldn't check.
