These images are from a tutorial about hand rendered typography and how to digitise those graphics and use them in our designs. The first image is a rough draft developing the basic shape of the letterforms, I then map that out with more care on some grid paper, measure areas and develop the strong letterforms. Once complete I stick the artwork to my desk, stick some quality tracing parer over that and trace the design with care to produce a very clean master. This trace is then scanned, adjusted and finally traced using the auto trace feature in Illustrator. This process produces a very clean results providing your tracing work is thorough. Once the lettering is converted to  vectors they can be treated in many different ways.
