By the time tourists visiting Liverpool leave, it is impossible for them to be in any doubt of the city’s link to The Beatles. They are all plastered on all the guided walks, each tourist information sign, every leaflet, billboard and, of course, they can be found in the museum.

This Thermos®-branded original metal lunchbox from the 1960s features artwork from the Yellow Submarine animated film on the front – and each side of the lunchbox features different scenes and characters from the film. When kids were munching their sandwiches from a lunch box like this 60-odd years ago, if they ever wondered if something like it would end up in a museum collection?
