The photo was taken in early 2015 by Camera Shy, a professional photography service based in Utah that specializes in family portraits. The image first appeared online when Camera Shy posted it to their Facebook[1] page on March 14th, 2015, with the caption "And sometimes bunny sessions go like this…" (shown below, left).
