I have seen this plate many times. It's on the Voyager space craft the one which is furthest from the Earth at this time. If aliens ever see this they will think our junk is small. I mean who did they choose for the model of MAN? And what is with his hair style? They will arrive expecting our women to have small breasts also. Maybe this is why they haven't visited us yet. I mean our directions are right there and women make all kinds of bad decisions regarding men on this planet so an alien has a chance.
