The King's Speech - 'Keep calm and carry on' inspiration

I'm fully aware that this design has become somewhat 'overused' recently (as the examples of variations show i.e. keep calm and rock on, and the fact you can buy a t-shirt in Primark with something like 'Stay calm and carry on' on the front), but I think the common layout works well as a starting point.
I don't intend to work with this type etc. but it will be an underlying inspiration in the idea generation process.
