A Rare 1988 'Shell UK Oil' Unleaded Petrol Information pack including an audio casette tape & accompanying Typed letter advertising the then New Unleaded Petrol 'Fuel of the Future' that was sent to petrol stations to get them interested in this new type of petrol that they would be selling, in this instance this information pack was sent to 'The Chief Mechanic' at Doncaster Engineering Services in south Yorkshire. There is some age related wear/marks throughout the outer card 'packet' and some creasing to the letter corners, Overall a rare surviving information pack of its type possibly the only one left as normally would have been thrown away (please see photos to see what you are getting).
