Souvenir

A souvenir (from French, for a remembrance or memory), memento, keepsake, or token of remembrance is an object a person acquires for the memories the owner associates with it. A souvenir can be any object that can be collected or purchased and transported home by the traveler as a memento of a visit. While there is no set minimum or maximum cost that one is required to adhere to when purchasing a souvenir, etiquette would suggest to keep it within a monetary amount that the receiver would not feel uncomfortable with when presented the souvenir. The object itself may have intrinsic value, or simply be a symbol of past experience. Without the owner's input, the symbolic meaning is invisible and cannot be articulated.
