Battlecruisers at anchor, probably in the Firth of Forth, with a tug and other vessels
The large vessel on the right is the battlecruiser 'Lion'. The group on the left is the battlecruiser 'Princess Royal' with a collier alongside and a battlecruiser of the 'Indefatigable' class beyond, either the 'Australia' or the 'New Zealand'. The date is 1917-18 and it is almost certainly intended to be the Firth of Forth.
