A souvenir (from French, for a remembrance or memory),[1] memento, keepsake or token of remembrance[1] is an object a person acquires for the memories the owner associates with it. The term souvenir brings to mind the mass-produced kitsch that is the main commodity of souvenir and gift shops in many tourist traps around the world. But a souvenir can be any object that can be collected or purchased and transported home by the traveler. The object itself has no real significance other than the psychological connection the possessor has with the object as a symbol of past experience. Without the owner's input, the object's meaning is invisible and cannot be articulated.[2]
