Smiths Crisps used to come with their own salt, twisted up in a little dark blue paper but they weren't in brown paper, in a white and blue bag if I remember rightly! We used to buy them at the local cricket match on a Saturday - lovely. I can remember my first ever taste of cheese and onion crisps - much more natural tasting than they are now - I think in about 1959 or 1960.
Anyone remember Invalid Butter Toffee - came in a tray, brittle, broken up with a hammer, and really crunchy in your mouth?
