'LEMFIZZ' Slabs of sweet

These tangerine or lime chalky slabs of sweet were another sweet item that came out [1980's?] that made you wonder why they decided on having monsters on the wrapper which had no real reason to, apart from monsters sell. When you think of monsters do you think of half inch think chalky sour sweets? Anyway these wrappers are pretty cool, I can't remember if there were other non-monster designs for Lemfizz.
