Scotch Express on the Forth Bridge

This 150 piece interlocking wooden jigsaw puzzle features the locomotive 1472, as she was numbered from 1923 until the 1924 British Empire Exhibition, for which the number 4472 and legendary new name of Flying Scotsman were adopted.
Here the locomotive is seen at speed hauling the express service across the Forth Rail Bridge, to the west of Edinburgh in Scotland.
