The one on Etsy is genuine. Yours doesn't have any kind of smooth leather "strap" running up and over the flap from the turnlock tab.
Please post more photos of the back and sides of the bag, also measurements. I haven't seen that style before but the creed looks valid. Is it a regular purse rather than a briefcase?

The one on etsy did have the "pebble" look that you mentioned earlier and the same stitching patterns. I can't find the exact bag anywhere. Not on google pics or ebay/etsy anyways. The zipper made me a little suspicious but i read that they used all kinds of different zippers throughout the years. Measurements are 8.5 x 7 inches. It's a small purse, kind of "clutchy".
