Don't know if you've seen it, but there's this new commemorative 50p coin doing the rounds. It's a nice bit of graphic design, and it's to celebrate fifty years of the NHS.
Now, I'm positive I'm reading far too much into this, but look. The old 50p: Britannia: she's wearing a helmet, carrying a shield with a Union Jack on it and a rather vicious-looking and downright pointy trident, and she's got a lion. A lion! The new 50p: fifty years of the NHS.
Is that not, right there, the history of Twentieth-Century Britain?
