The clothing strikes me as being set during that time or older, maybe the 50s, but I thought that was to give it a more patriarchal setting. It does resemble illustrations from that time. Maybe the fact that they are still wearing panties could also suggest that it is older, as their may have been some restrictions on what could and couldn't be published in magazines, or whatever medium this picture is taken from.From the style of drawing it looks pretty old. I'd say American 1960s or 70s, but I could be grossly wrong.
