This is an interesting one - I received this image in an email overnight. It looks like it could be the packaging for the December 10 DVD release of Angel: Season One.
I've done a little digging and this looks to be the same as the packaging on the DVD Street website. Interestingly it's not the same as the image used on the recent VHS Buffy and Angel releases as reported here last month. This one actually looks more like the Season One Buffy packaging - but that only holds three discs so it's going to be interesting to see what route Fox decide to do on this one.
