I like stereograms and when I came across this I tried it...my usual method is to cross my eyes so that the two black boxes become three black boxes. When I cheat this way, I can read Photo on top, and Reading on the bottom...however, when I just relax my gaze, the picture is too fuzzy to make out much...with a bit more concentration, I can make out the Photo on top, but not the Reading on the bottom...I dunno...
