I've enjoyed my pulp cover calendars from Asgard press the last few years. They are great -- authentic old covers of pulps and comics, and the design of the calendar looks great. Each month converts into a pinup suitable for framing. Great for gifts, too.
They have tons of them crafted from all sorts of vintage memorabilia. But the ones of interest to this community might be:
The Sci-Fi pulp cover one (this is the one I've sported for the past few years):
