Concorde early 1970s advertising poster. First supersonic passenger aircraft.

Note the number at the top right of the advert - this is the speed of the cruising Concorde - a staggering Mach 2.04 - speed of sound x 2.04. The Mach meter was also shown in the passenger area of the aircraft showing the passengers the speed they were traveling at.

Printed onto sheet aluminium (similar to what a road traffic sign is made from) and available in 4 sizes: A3, A4, A5 and A6. The technique makes the print completely waterproof. Comes with 4 adhesive stickers which will adhere the sign to almost any surface.
