If you are interested in keeping a musical instrument, for play or for décor, you should try looking into old pianos.

A piano is not only a musical instrument; a piano is a work of art to be treated as such.  Old pianos are no exception; they are antique pieces or old-fashioned pieces to be kept in a similar ambiance or to add some style to a modern decoration.

If you would like a piece for decoration purposes only, and are also in a budget, try not to go for antique pieces, since they will be substantially more expensive.  If you want it for music and playing purposes, you should have it checked out by a professional, since as they are aged they may have some missing or rusty pieces, or be broken down.
Maintenance is very import in order to keep your piano at a good reseller value, cleansings are important as well, so you can preserve all the pieces in a good state.
