On Valentine's Day 2012, I created some grade school style Valentine's Day cards but with characters from the first book/season of Game of Thrones. A few hours later, they had gone viral leading to an interview on Wired.com, Top 5 on Buzzfeed & the author, George R. R. Martin, posting them on his blog - and that he was "giggly".
I also did some prints with the characters from book/season 1 which are available for purchase at inprnt.com.
I also have these two pieces available as prints in three sizes.
