Not sepia, not suits and not (only) three men.
There is a story behind the postcard. It is one from a pack sold to raise funds for the Deal Memorial Bandstand Trust which was set up to provide a memorial for the 11 bandsmen who were killed in 1989 by the explosion in the Royal Marines Barracks caused by an IRA bomb. My neighbour who lives only a few hundred metres away remembers the explosion and resulting uproar very clearly.
There are concerts every Sunday and Wednesday throughout the summer in the bandstand in Deal, Kent, but each July a special Royal Marines concert is held in memory of those bandsmen. The pictures on the postcards come from the 20th anniversary concert. This year there will be another anniversary, the 25th.
The three plus one people in the picture are Chelsea Pensioners in their very distinctive uniforms. This means they live in the Royal Army retirement home, the Royal Hospital Chelsea. It was only in 2009 that women were first allowed so we must be looking at one of the first here, possibly Winifred Phillips. The scarlet uniform is worn on ceremonial occasions.
