Typeface I built to use for one of the cards. I was thinking about getting a photograph of someone handing the "Hello" to someone else, like on the street or in the train. I will have to tape or construct the letters together so they can easily be handed to someone.  

I also like the idea of having the type sitting on a train station bench or seat on the train. Since I don't have a camera to use yet i am just working with my kitchen chair for now to get an idea of how to set it up.
