WWI era tobacco jar featuring Bruce Bairnsfather cartoon

World War One era white bone china lidded tobacco jar featuring a transferred print of a Bruce Bairnsfather cartoon in sepia tones. It has a flat base, curved sides with a concave top and wide opening to accommodate the circular lid.
The cartoon on two of the sides is a well-known Bairnsfather image which depicts two soldiers standing in a trench with explosions and gunfire going off behind them, while Old Bill is seated and tells them 'Well, if you knows of a better ‘ole, go to it'.
The image on the other two sides of the jar show a bird singing while perched on some wooden stumps held together by barbed wire.
Around the top of the jar are images of a German military helmet, a water bottle, a British tin hat, an opened tin of plum and apple jam, a bucket full of holes, and an empty corned beef container being scavenged by a rodent, all separated by clumps of grass.
Around the edge of the lid are decorative depictions of Old Bill's eyes, nose and moustache.
The lid has a triangular metal attachment used to seal with contents of the jar. It comprises a central metal screw and metal springs attached to the three metal arms.
The maker's details appear on the base, along with an image of Old Bill, a number and a sticker.
