Mono Monday - Key or Quay

Another excellent theme set by Chantler63 for this week's Mono Monday challenge.
As there is no chance of me happening upon a picturesque Quayside any time soon, the choice of Key was easily made.  I asked T if he had any old keys somewhere among his jars of nuts, bolts, screws and oddments.  He found these, the purposes of which have been lost in the mists of time. I gave it a sepia tone to add to the aged look.
