I don’t often see English notes, living in Scotland and mostly using a bank card anyway. Some Scottish notes have wildlife on them, otters and salmon, and I like them, they’re beautiful works of art.
My previous passport had wildlife imprints on it, my current, burgundy, one has a mix of architecture, maps, people, artworks, inventions, transport etc. I’ve never really looked at it before, it’s rather lovely. I don’t know what the new-style passports are like. I’ll find out in 2029, when I get a new one!
