OMNI was both a science magazine and science fiction magazine. It contained articles on science fact and short works of science fiction, and ran from 1978 till 1995, read more about it at Wikipedia. As you might expect for a Science fiction Magazine it features some pretty unusual covers such as the above issue, the art here produced by Austrian artist Wolfgang Hutter http://en.wikipedia.org/wiki/Wolfgang_Hutter

What a great idea for a blog, keep it up!
The artist is Wolfgang Hutter according to this Flickr set:
