Dear Prime Minister, I write you regarding the typography on your house in 10 Downing Street. I do think that the two white digits on the dark door is quite beautiful. As I plan to remodel my own house in the style of 10 Downing Street, I have a question: What is the name of the font family you have used for those digits? Governments should not underestimate the importance of their typographic policies, and I am quite sure that many fellow voters feel the same way. Once my redecoration is completed, I will send you an invitation to my home so that you personally can inspect the typographic result.
