Professor's Door Sign

Many of you will be aware that Professor Martyn Poliakoff is now "Sir Martyn".

His door at the University of Nottingham's School of Chemistry has been changed accordingly.

I did not miss my chance and (with Sir Martyn's permission of course) have got myself a souvenir from all my years visiting his office to make videos!

The original non-Sir version - Sir Martyn signed the reverse side!
