having sourced most of my Disney steel's elsehwere, I was under the impression that most Disney titles were on the j-card's (discounting the earlier ones of Jungle Book, Aladdin, Lady and the tramp.
Then there are all the Marvel ones that certainly DONT have titles on the front(still disney) so counting ALL Disney, its far from the majority having titles, maybe more even a split(there are about 10-15 I dont have from zavvi out of the classic range)
Still, many dont and so you dont have a matching set anyway. Never will (and art only on the front is way better than art being ruined with a title)
Am all for adding the title to the spine but not the front.
