The "SwagDog Class Icon Custom T-Shirt Contest" was a contest created by SwagDog (a company producing festive t-shirts) and presented by Blizzard Entertainment in 2010. Apparently, Blizzard would post two questions on their Warcraft Twitter page each day, randomly selecting five winners who answered right to receive their class icon custom shirt.[1]
As originally described on the official World of Warcraft site[]

Through Tuesday, September 7, we'll be posting two questions every weekday on our Warcraft Twitter page that focus on key aspects of each World of Warcraft character class. For each of the ten class questions, we'll be selecting five winners at random from those who answer correctly to receive their very own SwagDog Class Icon custom t-shirt! The Class Icon line will be launching this Friday, September 3, and features re-imagined designs of your favorite class emblems. (Be sure to check the front page throughout the week for sneak peeks at all the upcoming icons.)
