Didn't your mother teach you that it's what's inside that counts? And what’s most important inside is your bones. 

Yes, every house needs a good foundation. Every castle needs its pillars. Any vertebrate worth a damn needs its spine. We’re talking about good bones, and what’s hotter than that? Beauty is only skin deep, but there’s nothing sexier than the curves on a good spine or a well-formed femur. 

Here are some bone models/model bones. Photos 1-14 are from the 2010 calendar issued by Eizo Medical Imaging Corporation. Photos 15-20 are from Miss Spine and other posture pageants from the 1950s. The rest are miscellaneous odds and ends from my spine collection (PS: my inbox is always open for spinal submissions).
