The map (image area) is roughly 25 cm x 20cm. With the mount the total size is 38 cm x 32 cm approx.

The map was produced for Dugdales England & Wales. Included on the map is the Newport, Abergavenny and Hereford Railway which opened in 1852, but it does not show the Worcester to Hereford line which was opened in 1858, so it must date from between these dates.
