One of the things I enjoy about vintage SFF illustrations is how it’s possible to pinpoint the time in which they were painted by how they depict hairstyles, clothing, and other elements. Take the image above. The woman has a fashionable hairdo like that of the Moonbase girls on the Gerry Anderson series UFO (1970) — and sported as well by many young women of the period — and she wears a silky blouse with poufed sleeves that were in fashion during the late 1970s. The being in back of her looks like a tall Jawa from the original Star Wars movie, which dates the artwork further to, or after, 1977 when the movie was released. So I would say it was painted in the years 1977 to 1980.
