Red buses and phone boxes are iconic – what are the less obvious but still ‘classically British’ designs seen in public life or at home?

The whole lollipop lady ensemble of the jacket, hat and sign feels particularly British.

Those old Neighbourhood Watch illustrated signs you still see have a British feel to them.

That 90s Smarties mug everyone seemed to have.

The Guide Dogs Labrador charity box outside newsagents.

What else?

EDIT:

these comments have made me feel more appreciative of the uniqueness of British design/culture and pleased to see that other people appreciate them too.
