Might be old news, but just checking out Pete McKee‘s website and noticed he’s now doing his artwork as iPhone cases. In light of the popularity of the Small faces case, thought it might be worth a mention.
A few designs on the site, but most relevant to this site are perhaps the two pictured here. The one above is the Away From The Numbers case with mod/scooterist image, while below is the the Great Labels artwork on an iPhone case.
One (big) thing to note is that these cases are designed for the iPhone 4 and 4S, so if you have upgraded to the latest phone, these are not compatible. But if you still have the older model and intend keeping it, the cases sell for £25.
