Can anyone identify the make of this 'Pangram' t-shirt?

[drtchock]

seen this really cool t-shirt.. its quite basic, the front is completely plain, but on the back on the tee there is this cool print, which is made up of pangrams (sentances with every letter of the alphabet), from how it looks the print reads...
