I think the entire
Gucci Ghost line will become iconic and collectable, especially the bags and pieces with with FAKE or REAL on. I'm keeping my 'REAL GUCCI' necklace.
Because:
They were one of the first collars that Gucci did with an artist
They were one of the first real pieces Alessandro Michele produced for Gucci (the Paddock and The Dionysus were already in the pipeline when Frida left).
They are very cool
They are recognisable
They are bold
They are a postmodern, artistic statement/comment on designer goods and status.
