sky paintings from the early 70s

in the early 70s i was working on a series of paintings that took their inspiration from the sky....infinity.....using the canvas as a window on the world.....depicting the landscape or world as a thin strip....with an overwhelming sky......i used the idea of a road or runway as a landing strip or landing area for angels or celestial beings.....the curtains either covered the landscape....indicating a closing off of reality....how can you prove that someting is there with out seeing it....it is about illusions of reality and imagination....space travel has always intrigued man....is the flying cube coming in to land or is it floating away....it has what looks like grass growing on its surface....note...appears to be......appearance can be deceptive.....
