1 drawing : pencil, with watercolour ; image 7.7 x 6.2 cm

Bears number in Lavater's hand: 21

Baur (op. cit.) suggests that the design (which in its full version includes 24 stages), which is a reworking of a series of 12 frontal physiognomies in the 1778 publication of the 'Fragmente' is much influenced by Petrus Camper's similar designs made in the intervening years
