It is not possible to release anything into the PD if there are any strings attached.The same goes for private property, trademarks, and visible logos: Would you like to see your private home displayed for example on an advertising column without prior notice? Nope? That's the reason for the so-called "Property Release". The object owner must give permission to use pictures of his/her belongings. But the Property Release also covers special cases, where designs or seemingly public buildings are protected. Examples are designs of new notebooks or mobile phones, as well as the Chrysler Building in New York or the London Eye. If you'd like to use pictures of that, the creators/owners must be asked for permission
