The one that I've seen had neither the clerk's "signature" rubber stamp marking nor evidence of a raised crimp seal.
You can't really make out any of those on the image that's on Fight the Smears because the sized it down considerably. However you can see evidence of both the embossed seal, the date stamp and the signature stamp in the high resolution versions which were posted on Daily Kos and Fact Check.
The high resolution version of the scanned image can be seen
here.
If you zoom in to the full image in your browser, you can see the horizontal marks of the embossed seal just above the date stamp. Also, portions of the signature stamp can be seen bleeding through just above the words "prima facie" as well as some above the words "fact of" in the text near the bottom of the document.
And of course there are the photographs which were taken of the document at Obama's Chicago campaign headquarters which can be seen
here.
There's nothing inconsistent between what's shown in the scanned image and the photographic images.
