K-ON! Japanese anime of the girl band

Anime "K-ON!" was broadcast on television in from 2009 to 2010.
This work gained popularity, it is said to have increased the Japanese girl band. 
I also like this artwork. 
When I clean up the room, I found a clear file that are not using. It has been printed Mio Akiyama of "K-ON!" 
She plays bass. While I play the guitar. 
Photograph is the file (^ - ^) 
Do you have ever seen a "K-ON!"?
 "K-ON!" is blessed with a particularly good song!
