These scary stickers, one of which you see here, came free in boxes of Weetabix, I believe in the late 1980's. There was I think about 5 or 6 in the set and they all glowed - in - the dark. I have another 2 somewhere which I'll try and dig out. The stickers came in a cardfold out which also showed the others in the set. The two pictures of the Vampire and The Werewolf short comicstrips were featured on the backs of the Weetabix boxes. There may of been others in these 'The Weetabix and the...' short comicstrips. You could get some really cool free gifts with packs of cereals, shame that is longer the case.
