This might sound like a dumb question, but did paper look like this back then, or is this just the result of it turning brown-ish over time?
If it's the former, when did paper start becoming white?
Do you literally not know that paper becomes like this with time? How old are you?

Paper turns yellow very quickly. Even leaving your morning paper out in the sun for a few hours is enough for it to turn yellow.

As opposed to figuratively not knowing paper becomes like this with time?
