The size of this image is making it a little weird. This one was clearly designed to be a full-sized poster, and unless you’re viewing the image on a very large display, it kinda puts the amount of convergence that your eyes have to do to make the image appear into the slightly-too-small range.
That means you’re likely adjusting your eyes to a point that doubles the correct convergence distance, and you’re getting a garbled image.
Even when you do get it, the too-small size will make the illusion of depth somewhat less effective than it would be if you were looking at it, in the intended scale.
Normally I can get these easily but my eyes just can’t work this one out
