This Saturday (8 June) I'm giving a tour of the collectors' market by Charing Cross railway station in London.
Starts at 10am, outside the northern entrance to Embankment Tube station.
It'll be like going to a museum - only you can touch (and buy) stuff.
So what's it going to be? Suffragette cards?
Snaps of Edwardian London?
Messages from WW1?
Nothing is too specific. There are collectors out there who only collect postcards of fireplaces.
