"Puericulture" by Man Ray (Emmanuel Radnitzky) (1890-1976) - Art Institute, Chicago, Illinois, USA.
Note: Puericulture and Pediatrics once were given equivalent
importance. Puericulture refers to the art and science
of rearing healthy children. With time, emphasis on diseased
children led to a neglect of Puericulture which represents a
premier form of preventive medicine.
Also note that the proximal transverse palmar crease reaches
the inner edge (away from the thumb) of the palm which is
called "Simian crease", a feature more common among children
with Down Syndrome.
