HD1 . Here's a representation of the Hornby Dublo 'Duchess of Atholl', from the old 'Weekly News' black and white ads. I've added the colour, and reset the text for clarity.
However, there is a technical error - can you spot it?
(Please note that the text is clear and sharp on the actual posters - the reduction to display
on screen has caused the smaller type to become fuzzy here.)
