German ad firm Butter wanted to prove that pin-ups weren't just for "craftsmen" with their latest ad campaign -- a sexy calendar far more at home in a doctor's office than ... wherever craftsmen hang out these days.
The calendar features models placed in seductive pin-up poses, then photographed to highlight medical imaging firm EIZO's newest "high-precision displays for the examination and diagnosis of radiographs." If you're into bony girls, and favor calcium over silicone, then these images will really do it for you. For the rest of you, they will probably just make you feel fat.
