Some interesting ideas chaps.
I don't think the Renault font is important really, the most important thing is that it is legible.
The "Powered by" seems popular and so on that basis what about this;
The printed size would be 24cm by 5cm. Printed white on clear static cling vinyl (no sticky glue).
If everybody is happy then I propose giving away 50 free
to the first 50 to request them, any further ones would then be available at cost which is about £2 each by the time P+P is included.
Let me know what everybody thinks.
