Funny sign for man cave real lab or even office. "Warning Mad Scientist at Work". Made to look "rusty" (it's not its part of the print).

Printed onto sheet aluminium (similar to what a road traffic sign is made from) and available in 3 sizes: A6, A4 and A5. The technique makes the print completely waterproof. Comes with 4 adhesive stickers which will adhere the sign to almost any surface.

I can send anywhere in the UK by Royal Mail.
