Fitting Titanic's tail shaft

In this remarkable photograph, taken in May 1911, shipyard men are fitting Titanic's starboard tail shaft.

In a most dramatic way, this image contrasts the enormous scale of Titanic's huge steel hull with the small human figures clambering over her. 

Look closely beside the man on the right.  There is a 'ghost' figure of a worker who has been deleted by the photographer in order to improve the composition of this carefully posed scene.
