On this subject I see there to be a certain poem to be spoken of, namely thus: "The Rime of the Ancient Mariner". Below is part of this long poem / ballad / epic sort of thingey.
'God save thee, ancient Mariner!
From the fiends, that plague thee thus! -
Why looks't thou so?' - With my crossbow
I shot the Albatross.
Samuel Taylor Coleridge 1772 - 1834
Of course the albatross, despite already having famous connections, is also known for its occurrence in Monty Python's Flying Circus. A 'Walls' ice-cream flag could within the realms of possibility also have a connection, before its present dwelling place behind some lockers.
