This is a solid brass sign that says 'PLEASE KNOCK & ENTER'. It has a black background and shiney brass lettering.
It looks like an old sign you would see on a doctors surgery door! But, it is brand new.
It measures 73mm tall, 58mm wide and 5mm deep. It weighs 150 grams!
There are no holes drilled for screwing so it would need to be glued.
