Gratispool Twilight

There used to be a company in the 1970's in Britain that you could send them your spool from your camera and when the prints were returned they included a free spool.I remember this company because they became involved in one of the worst industrial disputes in British history which revealed a right wing cabal who hand delivered peoples prints in order to break the strike.I mention this because the colouring in this photo reminds of this period.
