Plenty of differences between this Thor and the Marvel one. The one I found
the most interesting was that thunderstorms trigger the mortal-to-Thor
transformation. This comic is from 1959 and the cover is the work of Curt Swan and Stan Kaye.
If you DO go to your Local Shop tomorrow and flip through the new books don't be fooled by A+X #17. The Thor in that issue is a Skrull. This ad that appears in tomorrow's Marvels may interest you though.
