"In memory of the unfortunate sufferers who were drowned by the bursting of a dam at Bradfield, near Sheffield, on March 12th 1864..."
Includes also a verse whose first line reads: "Like crowded forest trees we stand...".
Similar to other cards produced at the time, though this one refers to upwards of 800 lives lost.
