London Transport Going Decimal leaflet, 1971
In 1971 the UK went decimal and changed its old, complex currency to one based on 100 new pennies in one Pound. For all organisations this was a huge operation requiring changes in prices, machines and cash handling systems. For London Transport the changeover was 'staggered' with Underground fares changing on D-Day itself, 15 February 1971, with bus fares gradually following over the the next week. In some respects one wonders if this wasn't more complex! However this leaflet was issued to school children (and their parents) the thinking being that us, at the time children, were quicker off the mark than our elders and so could help them out!
