Stanfords online as well https://www.stanfords.co.uk/historical-map-reproductions and in Covent Garden are also helpful if you are looking to shop in store.

Try giving Bryars and Bryars in Cecil Court a ring - they know all there is to know about maps.

Hi,
I bought a really old map from the Wandsworth historical society a couple of years ago. But it is newly printed, a reproduction of a 1787 map from British library. Very interesting to see the land pre the mass building.

Otherwise the Northcote Antiques market sometimes has some local ones. And eBay has quite a lot.

Good luck with your search

I want to buy my husband an old map of the area for Christmas. Ideally I want it to be an actual old map as opposed to a newly printed one if that makes sense. Has anyone bought one recently? If so could you let me know where? Thanks in advance!
