I wish to get rid of the Lion 10.7.5 AddressBook book-like interface a.k.a. leather appearance a.k.a. skeuomorphic design.
Usually this kind of setting can be change from the debug menu.
$ defaults write com.apple.AddressBook ABShowDebugMenu -bool true does not enable the debug menu in AddressBook.
How to enable this debug menu or make addresbook look like 10.6 Addressbook?
