Copyright/Designer credit on the footer

Looks like an edit was made to this site (http://rockymountainbrushcompany.com/) some time ago where the credit given to "catch themes" on the footer was overwritten. I am looking to change it so the credit is given back to Catch Themes but am unable to find where to do so. Ive combed through all of the php files and am not seeing it. Can someone take a look at let me know where I can make the update. Seems like every custom css trick I try to overwrite it doesn't work and the existing text lives on. Thanks, Ryan
