This Ainvention relates to a doll or similar ar

ticularly concerned with a doll having surface
portions simulating the feel of human skin and

The objects of this invention include providing
an article having a construction whereby portions
of the surface simulate the feel of skin, and pro
viding a simple method for making such an
article.; and particularly providing a doll of pleas
ing »appearance and durable construction in
which at least the body and limb portions have
surfaces simulating the feel of human skin.
Other objects'will be >apparent from the descrip
tion which follows.
Dolls and similar varticles are conventionally
made of life-like appearance fromthe standpoint
of both shape and coloring. Such dolls are nor
mally made from many materials including ilex
