There are quite a few cheap shirt sites online that sell cheap, printed t-shirts. The shirts are only available for 24 hours and the small print runs have allowed these companies to print fan art.
One of these sites is Teefury.com, which seems to enjoy producing t-shirts which have either fun or quite serious fan art.
If you like a smile or interesting poster art then Teefury’s gallery of previous releases is worth a look.
Here are a few examples –
Game of Thrones meets Masters of the Universe – http://www.teefury.com/archive/2394/CASTLE_GREYJOY/
Star Trek meets Futurama – http://www.teefury.com/archive/2222/Vulcan_Salute/
Games of Thrones – http://www.teefury.com/archive/battle/2203
I really like the fun of Castle Greyjoy , which is what would happen if the merchandisers for Masters of the Universe made Games of Thrones toys. Even the price tag has a clever comment.
