On off-topic Tuesday we feature this atmospheric image of the monumental dockyards at Birkenhead - opposite Liverpool - featuring the construction of the aircraft carrier HMS Ark Royal in 1950.

The ship took around five years to build, and the photograph captures her near completion but still surrounded by cranes. The image was published with the title ‘Where Great Ships are Built'.

Chambré Hardman set up a photographic studio in Liverpool in the early 1920s. With the help of his wife Margaret it went on to become a thriving business, specialising in both studio and street photography.

The photograph is part of a large and outstanding collection, and Chambré Hardman's studio and home at 59 Rodney Street in the centre of Liverpool are owned and run by the National Trust.
