There are several ways one could get results similar to the one in your example image. Among them:

• Use multiple exposures shot at slightly different angles and subject distances (or focal lengths).
• Use special effects lenses in front of the main camera lens, such as a "prismatic lens".
• Use a single exposure and post process it using different layers with slightly different magnification/cropping/tilting applied to that one image.
• Use any combination of the above.

Since the subject's eyes are opened by differing amounts in the example you posted, at least two exposures were used to make that image. Whether they were combined on a single frame of film before being developed, combined by printing two negatives to the same piece of photo paper in a darkroom, combined digitally using a camera with a "double exposure" mode, or outside a camera using post-processing applications, etc. would be very difficult if not impossible to ascertain.
