In my never-ending dedication to informing the world about foreign language editions of American magazines (here, here, here, and probably elsewhere), I offer up this link to a web site that displays some neat covers from the late, great Bob Guccione science/science-fiction magazine Omni.
These issues are from Japan, Spain, and Germany. I actually own two copies of the German edition of Omni, for which I paid a king's ransom in postage (photographed above). I also own a copy of the UK edition of Omni, which cost me considerably (and inexplicably) less. But, because Omni listed on its masthead many foreign editions, Guccione clearly had an aggressive international marketing plan.
Judging from the two German copies I own, it looks like Omni was smart and let the international editions include lots of (mostly?) local content, rather than forcing U.S.-created content down their throats.
