Topographical
views were especially popular among the rising numbers of mid-Victorian
railway tourists, and the firm of Thomas Nelson and Sons was able
to meet this demand by employing a mixed method of printing. A pen
and ink lithographed image, printed in purple ink, was then coloured
from two engraved wood blocks - one blue for the sky, the other,
brown for the ground. In later years, tints from stone replaced
the wood blocks to give more brightly coloured views, as in the
second example from 1900, produced by normal chromolithography.
