In the Seventies and Eighties, Yugoslavian science magazine Galaksija pumped out dozens of mind-blowingly weird covers that could easily be mistaken for prog rock LPs. Here's but a sampling of the many triptacular designs that hit Balkan newstands several decades ago.

You can see a treasure trove of these variegated covers at Yugodrom's Flickr page. Also, the design blog 50 Watts has a gallery focused on the illustrations of Russian artist Nikolai Lutohin.
