I am selling this vintage crisp packet:

Smiths Crispy Tubes in Cheddar Cheese & Onion Flavour with Fabulous Book Offer. 

Date on packet is 16 Jan 1988.

Opened a bit scruffily at the top and the bag is scrunched from manufacture. Please see photos. 

Despatched by 2nd Class. I will be listing more today... if you win more than 1 bag I can combine postage dependant on selling price.
