This week, Conservator Lynn Teggart from the National Library of Scotland describes conservation treatment of two large maps from the Bartholomew collection. This article was originally posted on the NLS blog.
The Newbigging Farm map
The first map shows Newbigging Farm and dates from 1864. Examination of satellite maps suggests that the farm still exists, and is based south west of Edinburgh close to Penicuik. The map is printed in black ink on a heavy weight, woven paper, with colour added by hand using water colour paints, and a layer of varnish applied on top. The paper has been lined onto a linen support, and wooden rollers are nailed to the upper and lower edges of the map.
