You said you found it after a long search on Google images. That thing surfaced very quickly after your bogus bc. What probably happened is the web site where your “birthers punked” thing appeared also had the Bomford bc demonstrating that it was used to make yours. I am not sure, but that may have been why it was so quick.
WHAT a coincidence! That's exactly how Koyaan exposed the fake Kenyan BC. Just dumb luck, right? LOLOLOL
Koyaan: I spent several hours with Google image search on that before I decided to broaden my search outside of Kenya-specific documents.
It was some time later that I finally spotted a thumbnail on one of the results pages that looked very much like the Kenyan certificate. I pulled up the full size image and found that it was virtually EXACTLY the same type of document.
