Hate to tell you, but that calendar's a fake. The 2004 Masamune Shirow calendar is called Japanesque, the image shown for the that 2004 calendar is actually one of the images from 2000's "Millenium" calendar, If i recall correctly.
As to the DVD's, The Masamune Shirow collection i'm positive is illegal. There is no possible way you can fit "Appleseed, Black Magic M-66, Ghost in the Shell, Dominion Tank Police, Gundress" all on 2 DVDs. I can guarentee you they will be of a sub-standard quality.
The Chobits DVD's i will entirely advise against buying. Notice how it says episodes 1-24. Chobits has 26 episodes and two special episodes, you aren't getting the whole series. Again, they're bootleg DVDs.
I mean, if you're not bothered with them being bootlegs, sure, pay for them, but personally, if i'm paying for a DVD, i want to be paying for a legit one.
*EDIT: Also note, eBay is notoriously bad with fakes and illegal DVDs. While they are a lot cheaper, they're very rarely of the high quality you expect of DVD.
