A large drawing on seventeenth-century French paper of a Putto in Flight bearing an old attribution to Poussin corresponds in size and design to a putto in Le Temps et la Verité, painted for Cardinal Richelieu by Poussin in the Palais Royal in Paris in 1641. Stylistically anomalous in the corpus of Poussin's known oeuvre, it "should" be a copy - perhaps by young Charles Le Brun, who was working in the same palace at the same time - though this explains neither its variations from the painting nor what kind of preparatory work was required for Poussin to execute Le Temps et la Verité.
