PORT OF LONDON AUTHORITY SOUVENIR OF RIVER THAMES EXCURSION 1916 WESTMINSTER TO CRAYFORD NESS 

A very rare, possibly unique, folding map of a trip down the Thames in 1916, 110 years ago. The boat would probably have been a paddle steamer. The card cover is a bit grubby, but the inside is excellent and very detailed. Please examine all the photos to see for yourself.
