Sheets 93NE and 93SE, Old Series 1" joined. Yorkshire, southeast. 1885
Sheets 93NE and 93SE, Old Series1". Two sheets joined. Yorkshire between Selby in the south and Howardian Hills in the north. 1858 and the geological information is dated 1885 for the south half. The north half probably has similar dates, but the information has been trimmed in the joining of the two sheets. 69cm x 61cm. Dissected and mounted on linen between standard Stanford's card covers; although the Stanford's label is not the cover, a small Stanford's label is pasted in the bottom margin. The colours are bright and clean, the paper is age toned, with slight foxing in the left margin, the linen is brittle and there are short tears of an inch or less in from the edge along some of the linen folds. Overall, it is in good condition for its age.
About the England & Wales One Inch Old Series
The Geological Survey of England and Wales used the Old Series of the Ordnance Survey topographic map at a scale of one inch to the mile as its basemap, initially. These engraved basemaps were published and revised between 1805 and 1885; the sheet sizes varied and the layout and numbering system were eccentric. The Old Series geological maps were hand-coloured and without geological sections, which were published separately. The GS of E&W published the Old Series from 1850 to 1900, when it switched to the colour printing and the New Series one inch maps. However, old stock of the Old Series continued to be issued, hand-coloured, until the 1930s.
