Take the following as truth: When a trompe l'oeil shaving brush and a match turn up later in the show in Magritte's Personal Values (1952), they have an oneiric suggestiveness quite in contrast to Murphy's flat factuality.
Then the following statement: "Magritte's Personal Values helped increase the sales of shaving brushes and matches." is true, false, or inconclusive?
Answer: Inconclusive
