Jango Fett, from the Star Wars Attack of the Clones 12" action figure line, was named Toy of the Year by Toyfare Magazine for 2004.
Also note a new advertisement from Hasbro on the inside back page of the latest Toyfare issue, which promotes the 12" action figure of Boba Fett. The ad uses new copy and photography.
[Update 2/2014: Reviewing this article, which we published circa 2005 (or earlier), for the sake of adding which exact issue of ToyFare, we only can find ToyFare #67 as their "Toy of the Year" issue featuring a 12" Jango Fett figure. That issue came out in 2003.]
