(Sort of on-topic)
Paizo publishing has a line of pulp fiction novels that reproduce some of the stories from the 1920-1950s & beyond. Many of these books have been out of print for a long time when Paizo picked up the rights. Not all of the line is science fantasy, but they do a pretty good job of describing the books.
I've read the one's they have from C.L. Moore, G. Gygax, & bought a few others (too little free reading time, ARGH). I recommend the "Northwest of Earth" by C. L. Moore for a mix of ray guns and fantasy magic.
You can find them here: http://paizo.com/planetStories
(I'm just a customer of that company, not in any way compensated for acting the "drooling fanboy" role).
Hope that helps, Max!
