That EBay looks real to me and me too,
pretty bad condition and single flap is not popular.
actually the pricing is quite reasonable.
I sold my vintage flap in vestiares for £1800.
I sold a Kelly 40 in Etuope , clemence leather for £3000, Excellent condition too, but I stupidly lost the strap and Clochette when I moved so it was priced lower.
the whole concept of buying designer bags and thinking you can resell them for way more is very misleading , the market is over saturated , sizes and designs come and go , colours get outdated pretty quickly.
