The painter Peter Brandon never dated his works, and their chronology is only now beginning to take shape in the critical literature. A recent dating of a Brandon self- portrait to 1930 is surely wrong. Brandon was 63 years old in 1930, yet the painting shows a young, dark-haired man- obviously Brandon, but clearly not a man of 63. Which of the following, if justifiably assumed, allows the conclusion to be properly drawn? ['Until recently, there was very little critical literature on the works of Brandon', 'Brandon at age 63 would not have portrayed himself in a painting as he had looked when he was a young man.', 'There is no securely dated self-portrait of Brandon that he painted when he was significantly younger than 63', 'In refraining from dating his works, Brandon intended to steer critical discussion of them away from considerations of chronology']
