Mystery designer logo purse

I have a mystery designer shoulder bag and I wonder if anyone knows which company made it. I've done a Google Image search upload--no luck. I've tried countless search combinations--no luck. It measures 7.5" x 6" x 1.5" (I even tried a "purse dimensions" search) and it's made of a thick, saddle-type leather burnished to a high sheen. I just love it, and I'd like to know who made it. Here's a photo of the mystery logo.
