I visited Bradford center years ago and it was a really bad setup. Appaling bad displays and very few viewable images and virtually none of the big namess on display. Gaining access to view any original prints was for the academic elite only.
I suspect this is the reason why they are being moved. The V&A has an almost opendoor policy to viewing any of their artworks in their collections. You can book a study room and request specificc works to view and they are brought to you from the vaults so you can view and handle them. The V&A is a far better place for them. Bradford can whine all it likes but theres no point keeping them there if no one is able to view or use them for research (unless they have a string of academic qualifications in a related field).
