Surplus original Ordnance Survey maps dating from 1904 to 1925 will be offered for sale at the Record Office in Harold Street, from 1pm to 4pm on Saturday 6 November.
The maps are on the old scale 25-inch-to- the- mile, each locality having its own sheet. Prices will be up to £10 per sheet, depending on condition. A wide range of second hand books on local and general history will also be for sale.
Rhys Griffith, senior archivist, said: 'Maps are such an
evocative way of showing how a place has changed over time. We
are fortunate to have so many spare to make available for sale.
Having an original map showing where you live is a great thrill
- it also makes a great Christmas gift.'
