My favorite Giuseppe Festino covers from near the end of his run with the Italian sci-fi magazine Robot. These are from late 1978 and 1979. Bold colors, bold compositions.
I featured Festino's work in my free sci-fi art newsletter a few issues back, so check it out for more info. The final one here, with the decaying robot, was for the last issue of the magazine, before it was rebooted in the 2000s.
