If you pick up Garth Brook’s Ultimate Connection at Target, and rip them for your favorite device, you’ll probably end up looking for the album covers.
iTunes wasn’t able to find them, but I searched the internet for them and you can download all the high-res album covers here.
They’re 1600 x 1600 so they should look good. Just right click on the images and open the link in a new tab to get the full sized versions.
As a bonus, I threw in the album artwork for Christmas Together with Trisha Yearwood.
