That sticker is just an NBA sticker, saying it is a genuine NBA Licensed photo, and has nothing to do with any authenticity of the autograph.
All NBA Licensed product will have one of those stickers on it, just like when you buy an NBA jersey, the tag should have one of those hologram stickers to say it is a genuine NBA licensed jersey.
Like others have said, unless you have a UDA Authenticity sticker with matching certificate, people will not believe it is genuine.
It may be an IP Auto, so could still be genuine, but would not be 'athenticated' to be an MJ auto.
