I'm not a signature expert but am a prints historian and it is a stamp. Stamps have a tell tale dark edge/rim around the edges of the printed graphics because the pressure of the stamp against the paper presses the excess ink to the edges. You can see the thin, uniform rim around in the image. Real handwriting can of course produce different levels of ink at different places including occasional dark edges, but the rim here is uniform an in many of the areas here where handwriting would overlap the rim only follows along the outside-- as with a rubber stamp.

I was an art historian for a British academic encyclopedia and am the author of the encyclopedia's entry on that form of printing.
