There's a resemblance, but he was 21 in 1927 (and his hairline is different).
That makes this off topic, but, the science and engineering library at the University of Rochester is named after Carlson (presumably it was paid for by Xerox, which is headquartered in Rochester), and there's a neat little exhibit about him with lots of photos and a reproduction of his famous first xerography experiment and first prototype xerox machine. I worked in the library as an undergrad there and looked at everything in the exhibit dozens of times (to waste time).
Anyway - if you look at the high-res photo at shorpy - http://www.shorpy.com/node/15583?size=_original#caption - the message on the paper appears to exist on the glass cylinder in the back as well. Wonder how it works.
