Personal items based on who's desk it will be. Pictures of wife and kids, old army pics (if you decide the desk is of a vetran, lots of ANZAC troops after the great war), extra cufflinks, etc.
Perhaps develop a personna for the desk of someone who might have worked at the town hall. That would turn the entire building into an accessory for your desk.
