Auctioneers can't be experts at everything I guess.
It's from the 1950s and it just says 'Gucci' because although was made after Guccio Gucci died (bag would be marked G.Gucci before) it was before Gucci went 'international' and all boutiques would have still been in Italy, hence no need to say 'made in'.
Gucci does NOT usually say real crocodile anywhere (can't see it on photos) but of course it IS real croc. The point is, Gucci don't don't do faux/stamped/embossed croc.
It would have cost a small fortune new, look after it. Your mother will be thrilled I'm sure
That's awesome! Really lucky I didn't get ripped off on my first ever even remotely 'branded' buy. I know nothing about brands but seems like Gucci has had quite a long and complicated history from what you've said. Hopefully I'll be able to bring it in to a Gucci store to repair it. Thanks so much!
