The upper case "MADE IN ITALY" tag indicates either 2011 or S/S 2012, before the alpha letter was added to the tag to show what season it was. Usually bags of that time had colour codes but this one doesn't. If I google the style code it pulls up several of these bags but all are on Asian sites. You know your Bals, do all of the other markers look good? Do you want to throw it on the AT thread and we'll take a look or are you comfortable with it? Not trying to freak you out or anything, there might be something I'm missing here. There are a few earlier bags with upper case lettering on the tag back and I don't know much about this style, if everything else checks out I suspect this is one of those. I'd be interested in seeing the details.
