Yes, it’s a giant Darth Vader, on the front of Melbourne’s Scienceworks Museum, shot in 2009.
The passer-by on the extreme right will give you an idea of just how large the Vader likeness is.
I do not crop, enhance or post-edit my images in any way. Shot with a Pentax K100D, using a Sigma 18-125mm lens. F11, 1/250 sec, ISO 200, focal length 34mm.
