One of the images in the remarkable Wellcome Collection:
Anatomical fugitive sheet (Viscerum...1539) bound at the end of Valverde, Vivae imagines partium corporis humani...1566. Part of the engraving is composed of printed paper flaps that, when lifted, reveal the internal organs of the figure. This is one of a pair of male and female figures... The work was originally published in Rome, 1556.Four additional images (the male and the female, unlifted and lifted) at the link.
