The ads you see here are all from the backs of Horror bags packets, of course advertising two of the products Bones and Fangs and the horror bags tagline 'Snacks that go crunch in the night'. I think that Bones and Fangs were the first of the 4 product line. I still have yet to see a packet of Fangs and Bats that I could put here in The Cobwebbed room. Surely you would think that their is some sort of archive that Smith's crisps has of all their products, including packet designs, advertising, promotional items etc. Certainly on the net their doesn't seem to be anything, maybe someone knows differently that could share it here.
