The composition, the bodily structure and the interrelations between the characters in several drawings of 1902 and 1903 evoke La Vie and the painting underneath Barcelona Rooftops. One of them, made in March 1903, is the link that connects this hidden couple to the final couple in La Vie, for the position of the woman is a variation of the female nude in La Vie, and the bearded man matches the figure revealed by the X-ray of Barcelona Rooftops.
