A Collection is dead when it is a collection to which nothing can be added and from which nothing can be removed!.

A Collection is always more than is necessary. It is a material concentrate that continually stimulates, that overexcites because it is already too much. The collector's need is precisely for excess, for surfeit, for profusion. It's too much and it's just enough for the collector.

Mail is an invention that resulted in millions of pigeons losing their jobs and ending up on the streets.
