Titanic Survival Biscuit

For fifteen thousand pounds it sold,
the cracker that's one hundred and three years old,
it's the world's most valuable biscuit,
part of the Titanic survival kit.

This snack has outlived the last survivor,
shame it didn't prove to be a life saver,
now only the ghosts walk on the waves,
as the bodies lie deep in their watery graves.

Biscuit:  Old stale box of Palmiers - nearly passed their sell by date
Taste test:  Not bad considering their age.
Cost: Cheap - from Lidl a long time ago
