This bag is from summer 2011, and was actually made in February 2011.There is a lot of misinformation out there, so I am going to work on a guide to help answer some questions about vintage Coach products.A lot of information gets lost with time, and even Coach couldn't answer some of the questions I had when I began my collection.It says "Handcrafted in China", which is where most Coach bags are made today.
