J G Bartholomew & Son, Half-Inch to the Mile maps of Scotland, 1926-1935

These maps at half-inch to the mile (1:126,720) were based on larger scale Ordnance Survey mapping, particularly the Popular edition of 1921-1928.

Bartholomew's had published their 'Reduced Ordnance Maps' at this scale from the 1890s, and their success and subsequent editions made them a trademark series for Bartholomew. The maps were also included within Bartholomew's Survey Atlas of Scotland (1895 and 1912).

With each sheet covering approximately 45 x 60 miles, the whole of Scotland is covered in 29 sheets. The attractive layer colouring of relief, from light green through increasing shades of brown, to white for mountain tops, was both innovative and influential. The famous Bartholomew map publishers, had been based at Duncan Street in Edinburgh from 1911, and by this time were under the control of John (known as 'Ian Bartholomew (1890-1962).
