I've had two Street bags, both with classic HW though. If you compare the Street pic you posted the front zippered pocket sits higher on the Street than on your bag.Mine has no pocket on the back, hence my confusion. This one on The Luxury Closet has the pocket, but is otherwise quite similar with the GSH. Its tag number is 224902. https://theluxurycloset.com/women/balenciaga-purple-leather-giant-street-bowler-bag-p90
