I've seen this same Michael Jackson signature style repeatedly showing up on eBay through (at least) 3 "different" seller accounts over several months time. The sigs are always on either vinyl or vinyl covers.
Sellers are all located in the UK. (my internal warning alarms are going off all over)
Forgive me if this has already been exposed as one of the mass forgery rings. I am still catching up with all you have uncovered on MJ signature fraud.
