Dragon-Con the North America genre convention that takes place once each year in Atlanta Georgia has listed almost a dozen items on Ebay for their various charities such as autism and conservation.
“Since 2005, Dragon-Con has raised almost $224,000 for its official charities, which change each year.”
The items are autographed photos and posters from Amanda Tapping of Stargate SG-1, Wil Wheaton, Eureka Cast, Avery Brooks and more. I have posted a link below that will take you directly to the Ebay auctions of Dragon-Con. The 27th annual convention is August 27th to September 2nd 2013 and will host guests such as Richard Dean Anderson, Avery Brooks, Erin Gray, Richard Hatch, Lee Majors, Allison Mack, Kathy Najimy and dozens upon dozens more!!
