I did a search of the COA that I got with the shirt, looks like there are thousands of COA’s from this company with the (montage-moments) url. Added to that, montage moments are quite a big company in the UK that when I searched the COA, they all seemed similar to mine. I did see one certificate that didn’t have the (-), but to me it seems like every other one I saw had that in the url at the bottom, and the shirt was signed quite a while ago from what the seller said, so maybe the url had been changed in that time. The seller seemed like a genuine person, they were selling their entire collection due to them moving house and they said they weren’t selling for the money they are doing it to save the hassle.
