(A fictional scenario...)
So, the premise is that, unknown to the world, some media footage (still photos, audio, film and/or video) of a momentous event was captured in real time. The person capturing/storing/archiving the footage put it away shortly after capture in a footlocker or the like, and before bringing it public, died tragically. The footage was stumbled into by a descendent or researcher or whatever in 2023...
(Also, the point here is NOT that the footage necessarily changes history in the, "actually, you thought X, but really Y", but moreso, what SUBJECTS would be interesting. Sure, history could be tweaked, but that's somewhat secondary to the shock of the discovery. Presume that the footage can be verified as being appropriate vintage. Means of capture not entirely ASB, but can be pretty close...)
