The $10 t-shirt deal of the day over at RIPT Apparel is a mash-up of Doctor Who and Superman called “Super Who” by artist Bamboota.

The sale at RIPT began today, Friday, May 27, 2011, at midnight CST, and will continue for 24 hours from then, and once it’s over, it will not be sold on the site anymore.

Of the design, the artist said, “I thought it would be funny to make it seem as if Superman was in a haste to defeat evil and didn’t realize that he stepped into the TARDIS instead of a phone booth by accident!!”

The t-shirt is available in men’s and women’s sizes for $10 each in royal blue. Kids sizes are $15 (Boys, Girls, and Toddler in royal blue/blue); Onesies are $18 (in powder blue). You can also get the design on a Hoodie for $38 (in Men/Unisex sizes in royal blue).

What do you think of this design?
