I can't imagine what a bottle made into a lamp must look like if all the lamp components are on the outside of the bottle. What is used to hold it all together? Hose clamps, duct tape?
At any rate what you have is a curiosity, but nothing more. I'm going to guess that 1972 has something to do with the age of the wine, although that is not necessarily so.
It is of passing interest that your label has French (vin rouge), Italian (chianti) and German (rotwein inhalt) words on it. Just passing interest.
This bottle of wine or lamp is worth whatever you paid for it.
