I can be fairly certain when this was taken and where it was taken. I remember the day well : that is my brother Roger on the left and me on the right. It is 1969 and we are in Maidstone Market in Kent trying to earn an honest crust by selling an extraordinary product mix of sea urchin shells and maps of the Upper Medway Navigation. I am not sure where the bulk supply of shells came from, but the maps where drawn by my brother. I was amazed to discover (isn't the internet wonderful!) that those maps are still on sale today although the price seems to have gone up a little. But I have no idea who took the photograph. Roger, if you are reading this, can you remember?
