There is nothing sinister about the gray hooded sweatshirt anymore, no mystery behind the aviator sunglasses.

Once, they were among the hallmarks of Ted Kaczynski, the anarchist Unabomber who killed three people and injured almost two dozen more during a nearly 20-year reign of terror. Now, his old clothes adorn a mannequin in a sterile government office in an online photo tagged Unabomb0001.

This is the first of 51 lots of Kaczynski’s personal belongings that the government will auction online next week in what amounts to Uncle Sam’s version of eBay. The bidding begins Wednesday, but the Justice Department has posted pictures of the goods to its Flickr stream to drum up interest — a final swipe at a man bent on stopping technology in its tracks.

The auction is part of a court order finalized last summer to sell off Kaczynski’s property and turn the proceeds over to victims of his attacks. There will be no reserve bids and no price ceilings. Instead, it will be up to the public to determine how much the remnants of Kaczynski’s life are worth.

His original, handwritten anarchist manifesto is photographed as Unabomb02. Unabomb42 shows the hand tools he kept stowed in a box of Tide detergent. Unabomb19 features a tan duffel bag. The items are housed at a Government Services Administration outpost in Georgia.

The government regularly sells property it has confiscated from nefarious dealings. But rarely is there an auction like this one. Federal authorities seized the items from the wooded shack where Kaczynski lived in Lincoln, Mont., after he was arrested 15 years ago. These are not the spoils of a life of crime, but rather a grim documentary of his gradual descent from child genius to domestic terrorist.
