The $9 t-shirt deal of the day over at Teefury today is The Dark Knight-inspired “Heath” shirt, by artist Lee Crutchley.

The sale at Teefury began at midnight EST (Saturday, January 8, 2011) and will continue for 24 hours from then, and once it’s over, it’s gone from the site for good.

The design is of Heath Ledger as The Joker from the popular Batman Begins sequel, The Dark Knight. In the face are the words, “Why So Serious?”, The Joker’s famous quote from the film.

The limited-edition t-shirt is available in Men’s and Women’s sizes, both in White color.

Here’s what the artist had to say about the design.

This is still one of my favourite things I’ve done. Batman has always been my favourite superhero and I thought The Dark Knight was amazing and Heath Ledger was awesome as The Joker! This was the first one of my Quoteskines that sort of got noticed. It was posted here and there when I first did it and as a result it was the first time I had a wave of people start following me on tumblr.
