I so recall all those fab mail-away gifts from ice lollies in the Sixties including this Zoom Wall Chart advertised in TV21 in April 1968 with the help of Alan Tracy. You got a free badge too but I've no idea what that looked like now. Anyone have the full chart and badge?
To remind you, the chart was of all the space bases and missile bays in Nineteen Sixties Britain. I wonder what a similar wall-chart would look like today? Do we have anything left?
