Many, and varied descriptions on the internet as to what this tin actually appertains to.
Some say WW1 related others it commemorates a royal event. (Christmas 1915 is mentioned often).
The painted image to the lid is very much of the type related to WW1/early/coronation vintage rather than a later jubilee.
The inner under lid is with a good printed detail, ‘obverse’ lid with very good bright colour and detail, with minor paint fragmenting/marking.
Nice looking item with hinge in good working order
