OO that's kind of you to try. Mine has a very definite "M" on it. I've bought it pre-loved but my concerns are growing about its authenticity. It is a 2006-2008 bag. The thing is the authenticity card has the little grey sticker but the CC logo seems a bit off-center to me so I'm just hearing warning sirens. Would be great if someone had a similar bag so we could compare. xThis is my marking. I cannot make out what it is.
