The copper plate has not been located. It has an exceptionally broad, narrow horizontal format. The only etching that is wider is Whistler's biggest print, The Palaces [223], and dates from nearly twenty years later.
It was not, however, the first in which an extreme horizontal format had been used. Thames Warehouses [46] and Old Westminster Bridge [47], both dating from 1859, are on Hughes & Kimber plates measuring 76 or 77 x 204 mm. Clearly the shape of Westminster Bridge itself dictated the choice of plate shape and size.
