Chipmunk OXO Crisps I have some very fond memories of Chipmunk Oxo crisps. In the 60s we sometimes went to Norwich indoor swimming pool (I come from Gt. Yarmouth, where the pool was uncovered, unheated, and absolutely freezing). You could buy Oxo flavoured crisps from the vending machine there. The only flavours generally available at the time were plain and cheese and onion. I felt kind of privileged to eat something that few others had enjoyed.
