On his Facebook page, the writer Steve Duffy “isn’t quite sure what’s scarier: that this Tumblr thread exists in the first place, or that over a thousand people are fans of it.”

Hold that thought, for there are 1,000 fans (and counting) of Pinup RDJ, which is run by Lisa aka Saxifragious Personette, who writes:

“Vintage pinups are the pinnacle of art. Robert Downey jnr. is the pinnacle of sexy. It’s not rocket science.”

You know, she may have something here.  This is one we’re going to have to ponder.  Answers please, on a postcard.  In the meantime, enjoy Lisa’s incredible handiwork.

With thanks to Steve Duffy
