This designed was originally used for "Karr" (Kitt's evil twin") but was then used for Kitt as the series progressed.
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.
