The details on Obama's Long Form Birth Certificate from 1961 will have been typed out using a typewriter.

Tickerguy Karl Denninger says, 'Find me one typewriter in the world, anywhere, that can perform kerning and I will believe this "certificate" is real.

For the uninitiated, "kerning" is the process of manipulating the spacing of letters to make the appearance more pleasing.'

I only provided a link to the website above because it had information about duplicated pixels/letters/numbers in the Obama Long Form Birth Certificate. Giving a link to the page does not mean that I agree with the colourful language used to describe Barack Obama or any of the conclusions that the woman who wrote the page reaches about him.
