Sans reading the comments or Google-searching the image, honestly post what you see, if anything, then exercise either or both of the taboos to see how close you came to what folks are flocking to to see first-hand.
Hint: Focus on the image's near-center.
Hint: It's not porn (unless you turn the image upside down).
EDIT: I forget to add that I see the Maltese Falcon, albeit that's not it.
