The Doomsday Collection

[gettodamoofies]

Hopefully someone who owns this title can help me out on this one as I've searched on this site and others but can't see anything which confirms what I want to know and there doesn't seem to be a thread about this release.

In this case all I want to know is whether the three titles housed in this collection are actually the standard releases in their own cases with cover art or whether they are in a three disc case. The second picture on Amazon shows single cases on the spine, but Amazon images aren't always accurate.

If anyone can help out that would be great appreciated. Considering the exchange rate at the moment, if they're in their own cases I'm in!

Thanks in advance!
