The Golden Sun-Disk of Wadjet
The Broken Arrow of William the Second
The Golden Amulet of Haakon II of Norway
The Splintered Sculpture of John Boson
The Four-Starred Badge of George Marshall
The Stained Tie of Martin Luther King
I honestly think Martin Luther King could work if you do it right. Just don't do it about the assassination--that would seem distasteful.
As for replacement artifacts, feel free to use any of these that I made up:
The Empty Wind Bag of Odysseus
Niobe, the Weeping Rock
The Chipped Boulder Piece of Sisyphus
The Armrest of Casseiopeia
The Battle Plans of Mad Anthony Wayne
The Blood-Spattered Necklace of Lady Jane Grey
The Gold Bullion of Fort Knox
The Cotton Bale of Eli Whitney
The Captain's Wheel of Robert Fulton
The Discarded Petri Dish of Alexander Fleming
The Soiled Surgeon's Rags of Joseph Lister
The Stripped Electrical Wires of Alessandro Volta
The Eerie Sheet Music of Johann Strauss
The Guitar Fret of Robert Johnson
The Spat-on Uniform of Jackie Robinson
The Dragon-Headed Scepter of Olaf the Red
Just give me credit!

The Incorrect Painting of the Ching Dynasty
John Boson is off, and "The Incorrect painting of the Ching Dynasty" is up. It's gonna be a made up legend, along with the "Chinese Fisherman" one, but I've got the latter planned out well and don't really wanna put it up on the "red list".
If Martin Luther King gets one more bad vote, I'm gonna take it off, I think.
