This is issue #1 of a cheap sci-fi magazine that lasted 7 issues. The '6 Gigantic Star Wars Posters' emblazoned on the cover is a bit cheeky as the so-called posters are merely black and white full page illustrations and seem to be part of a promotion for a 'Star Wars Portfolio' by artist Clifford Bird which can be sent away for.
The rest of the magazine is a pretty good read with info on upcoming sci-fi flicks like Superman (1979) De Palma's Carrie follow-up The Fury (1978) and the Invasion of the Body Snatchers remake (1978). In an interesting parallel to the present cries of 'Hollywood has run out of ideas!' the writer calls for more originality in sci-fi films even to the point of dismissing the inevitable Star Wars sequels as mere cash-ins. I suppose back then the idea of a sequel matching its original in terms of quality was unheard of and nobody could have predicted just how good The Empire Strikes Back was really going to be.
Elvis Presley died less than a year before this issue's publication and pages such as the one below make greasnapshots of the time period.
