Alexander Munro (26 October 1825 – 1 January 1871) was a British sculptor of the Pre-Raphaelite movement. He concentrated on portraiture and statues, but is best known for his Rossetti-influenced figure-group "Paolo and Francesca" (1852), which has often been identified as the epitome of Pre-Raphaelite sculpture. Using only the above description and what you know about the world, "Alexander Munro did his most famous work after he was thirty years old." is definitely correct, incorrect, or inconclusive?
