The answer to this question depends on your goals. If you simply want something to fill a blank wall, a reproduction might be your best approach.  However, reproductions lack the aesthetic qualities of the original. Original authentic objects carry imaginative power from their associations in time and place. A mass-produced object, fundamentally indistinguishable from other members of its production run, will suddenly gain value through its association, as, for example, a baseball that happens to be used for a historic play. For many, that association is powerful. Like a piece of authentic Louis XV furniture, a map published in the 18th century in France has a history: it has survived revolutions and wars along with the everyday dangers of accident and decay. In the 1930s, Walter Benjamin famously argued that original works of art had an “aura,” an authenticity related to its time and place. It is this aura, this authenticity, that makes antiques special. It is possible to buy a modern reproduction of an authentic antique. But that reproduction has none of the aura of the original work, none of its imaginative power.
