Whoe remembers blackcurrant cupids, they were mauve coloured custard creams, blackcurrant flavour and instead of having a diamond embossed on top like regular custard creams they had a little cupid with his bow.
Also my favourites as a 5 year old around 75, 76 were Malted spooks, they were round coloured biscuits full of malt they even invented spook characters that you got stickers of, the thing I remember the most was the amazing colours of them that blue and proper intense green, yellow and red, they wouldn't get away with half of what must have gone into those today,
And finally one quick one, Nursery rhyme biscuits, like sports biscuits but with characters of nursery rhymes on, they also made some in the 80s with traffic signs on them.
