Limited edition type A is seemingly the most plain of the 3. And it having the DVD as a bonus while the others have more collectable items such as booklet and a card make it seem that much more plain. The poses on the cover of the type A release are the best though especially Tanakachi, Mikitty, Aichan and Kamei! The whole group looks absolutely smoldering on the covers!
It's Limited edition type B that is the best and not surprisingly so. The slipcase and cd cover are both great looking and the 40 page booklet really raises the bar as far as pics of the group are concerned. Sorry I just shot these with my camera and I'm sure Tom will have great looking scans on his H!P blog (helloblog.co.uk). From the first page when you see Mikitty!!! you know this is going to be special. She and everyone else looks incredible! All of their outfits are perfect as well! Below are shots of the booklet.
The regular edition has a nice look with the black borders and the first pressing comes with a photo card with a nice group shot.
