Above are well-designed anatomical typography posters by Mattias Sjöberg. These would make a nice little V-day present or addition to your own art collection!  See his description below…

The inspiration for these posters came from the expression “to be beautiful on the inside”. And if you think about it, we really are! I live the organic but still graphical shapes of the organs and that there is so many feelings and associated with them such an love for the heart and intuition in the guts.
The posters are typographical pictures built with words associated with the hear and the lungs offset-printed om 170g paper and more are coming…
