A superb collection of photos of Hemel in the 1970s has just been sent to us.
They come from Dave Firman and, as he says, include some real corkers.
But Dave doesn't know who took the pictures and they also include some other 'mysteries.'
Who was this man protesting in Times Square over the "Scandal of Grovehill" and more homes needed for the young?
