I've fixed the typo on the sleeve for Hand In Glove. For future reference, all the artwork files are uploaded to my Flickr stream, so you can grab them there. Click on the image you want to replace, and go to actions > view all sizes > original, then click download.
Handy hint: you can often get a sneak peek at what's coming if you check Flickr. The artwork goes up there before the files go online.
