Back in the mid seventies there was a marvelous large format (11×16 inches) monthly magazine in the UK dedicated equally to both science fiction writing and science fiction art. It only lasted a couple of years, but by happily coinciding with my formative teenage years it left a lasting and deep impression on me.
Whilst I unfortunately lack a scanner large enough to scan my own magazines, I have found a link to a gallery of the front covers that gives you a glimpse of what lay within.
