Of course, the advantage to a Wiki is that we can change our content to match the mores of the times, unlike a print object. If this was 1972 we could link to the image, and then in 1990 we could inline it. No content lost. Nobody too confused.
I take your point, but I think a lot of people might have found it a bit odd. We Brits had been used to seeing Vitruvian Man in the opening credits of a weekly current affairs program for half a decade by then, so linking the Pioneer plaque would probably have seemed a rather silly thing to do. I think many Americans might have thought the same, too.
