Hi .. thanks for your post on the Jackie Chan Collection .. most of the covers you have listed are not "missing" .. it's just that there is no high quality artwork out there for them .. they will be added as soon as I can source something :)
Since you have stated that you have these covers I would appreciate if you could scan them and send them on to me or post them on the site so I can use the cover artwork and add these "missing" covers to the collection :)
