I am trying to figure out what font was originally used for the "Keep Calm Carry On" Poster

Keep Calm  Vorgeschlagen von fonatica 


Keep Calm And Type On  Vorgeschlagen von marijnkampf 

Alternatively you could use the Keep Calm and Type On font from http://www.keepcalmstudio.com/font. It has both the crown and the upside down crown included. I've specifically designed it to match the font from the original Keep Calm poster.
