The $9 t-shirt deal of the day over at Teefury is a Firefly-inspired shirt called, “Serenity Sake” by artist Ian Leino.

The sale at Teefury began at midnight EST (Friday, December 10, 2010) and will continue for 24 hours from then, and once it’s over, it’s gone forever.

The t-shirt design is for the fictional product Serenity Sake and includes the spaceship Serenity from the scifi television series Firefly and its big-screen sequel Serenity. The background is similar to the round Serenity logo (and has the same Chinese characters at the bottom). The bottom of the shirt says “SERENITY SAKE With just a touch of Saffon.” (Saffron was a reoccurring character on Firefly). At the bottom right is the flag for the Alliance, along with a warning.

The limited-edition t-shirt is available in Men’s (including 2X) in “sand” color and Women’s sizes in “Natural” color.

Here’s what the curator had to say about this acquisition:

Firefly might be the greatest one season sci-fi series in history. If you haven’t seen it, you owe it to yourself to rectify that immediately!

I agree!

Leino also did the Doctor Who Who’s Who t-shirt design. Be sure to check out his side art on the sale page, very cool!
