THE SECRET SOFA

I first came across Father Unwin's original Secret Service prop sofa on this old Gerry Anderson props site http://www.gerryandersonprops.com/models.php

The owner of the sofa has it featured further on his own cool modelling site. Here's a modern replica Father Unwin by Duncan Willis on his original Century 21 prop sofa. About half way down his site.

There's more photographs of the sofa here too

Have you any Century 21 props like this or maybe Century 21 offices ephemera like notepads or letterheads?
