The painting is called "Mr and Mrs Robert Andrews."  Completed in 1748, critics consider it one of artist Thomas Gainsborough's finest.  It shows a slender gentleman next to his young bride, gun in hand, dog at his heel sitting beneath a tree and a nice country backdrop.  Rather innocent right?  But a closer look reveals some rather randy images. "The Telegraph" reports the piece is littered with phallic symbols and mockery rather than a picture of love and pastoral joy.  Gainsborough had once been friends with the couple, but the relationship soured, leading the artist to sneak gentle jabs into the work.  

The painting hangs in the National Gallery.
