Although bookends make great gifts, they don't come first to mind when people are thinking of something unique or interesting to give somebody that seems to have everything. You know the type of person, who has the Rolex, the jewelry, their home is stuffed full of all the normal gifts, and they aren't into sports.
However, most people read, and even if they don't have everything, bookends are a good choice simply because of the variety of designs and prices available. A set of bull and bear bookends would be an imaginative gift for a stockbroker for example. So they do make a good gift, and are also good for offices, businessmen, and professionals to enable them to keep the books they use most on hand.
The fact is that most people have a book collection of some kind, and they generally own a few books of which they are particularly proud. They might like them to be on show to indicate how eclectic they are in their reading, or they may even have an expensive rare book collection that they want to display. A nice set of bronze book ends, such as the popular thinker bookend set, is ideal for that, because they can display their books on a sideboard or mantelpiece rather than have them stuck away in a library shelf out of sight. Check out some ideas on which bookends might work for those on your list.
