Something happens when people hit their 30s. Sure, there's the indignities of aging. But there's also the overwhelming allure of nostalgia.

Coupled with a statistically likely increase in expendable income, it's basically a blueprint for ... this The Art of He-Man and the Masters of the Universe Limited Edition Hard Cover art book, being published by Dark Horse Comics this week.

Limited to just 4,000 copies (surely there are that many people who fit the above criteria), this 400-page ode to Prince Adam and his buff counterpart He-Man is the stuff nostalgia lives off of. Gone are the days of squishy-headed action figures and Saturday morning cartoons. You're an adult now, with an Important Job. Sure, this is basically a grown up action figure playset ... but it's also an art book, with a production quality to back that term up. And at $130 retail, it has a price tag to back it up as well. But we suspect you know if this is the product for you or not and, in the event you need some visual aids to help you make that determination, we're here to help.
