eBay seller Komanac is flogging this 4' high, 5' long AT-AT model made of wood, cardboard, duct-tape and Sharpie: "This was created for an art show: 'Star Wars 33&1/3 anniversary' during Art Walk here in Lethbridge Alberta. I would love to keep it but not enough room. It was created July/August of this year – it took several rolls of duct tape and 30 – 40 hours to create."
