Whoever allows this to persist.
I'm not especially OCD but this has bugged me for years. There's no font I know of where the Zero is shorter than the number One.
Why does perhaps the most photographed house number in the world have to look so shit? It's as if whoever was doing it had a box of numbers and mounted a Zero from the wrong (smaller) set alongside the One & didn't even bother to align it vertically.
(actually, it seems it's painted & repainted on so the crime is repeated each time it's done.) Cunts.
If I were PM it'd be the first thing I'd sort out. Everything else could wait.
(lifted from last night's debate studio)but is the signwriter who does it at Downing St permanently drunk? It's all over the place.
