I've seen the scan of Paul Hoeffel's fax over at Kent's website. If I understand it correctly, you created the scanned JPG and sent that file to Kent and others.
I'd like to suggest something to improve the credibility of this thing - namely, to create a higher quality JPG from the original document. JPEG is a "lossy" compression format and is not very suitable for black and white, typed documents or anything else with high levels of contrast. The higher the compression level, the more likely you'll get strange effects - in this case, a noticeable grayish pattern around the letters and specifically the UN letterhead. I'm afraid people will cling to such details to quickly discredit the entire thing as a cut-and-pasted fake.
Could you try to scan it right into a lossless format (such as GIF) or a high-quality JPEG? Good image editing software allows you to change the JPG compression level before actually saving the picture.
