2008 Top One Hundred Countdown # 35: Composite Memorial Cabinet Card, Factory Fire, Nineteen Dead, Reading, Pennsylvania
From the infamous New York Gallery in the infamous Reading, Pennsylvania, a true memorial. Seems like there was a fire at some sort of factory or mill, and nineteen perished. The serrated edges of the card date this photo from the 1890's. Well, the light slash at the bottom says, "copyrighted 1888," so you Demonic Mistake Finders, there's your first mistake.
