If you love the pulp magazines from yesteryear, and are also a conisuer of fine pin-up work, then head over to the Website at the End of the Universe and download the free 2007 calendar.
Decades before Princess Leia ever wore her metal bikini in Return of the Jedi, women frequently modeled fine metallic swimwear on the covers of pulp science fiction magazines to excite the imaginations of impressionable, young readers.
This calendar does not have secular holidays or events on it, but rather features the birthdays of different sci-fi authors, editors, and artists. I’ve already downloaded mine!
