This autograph comes from a signing session organized by the agent of the actor or actress mentioned here. A photo is taken for each series of signatures depending on the item being signed. A numbered hologram is affixed to each object, and thanks to this hologram, you can verify the authenticity of this signature online, as well as the dates and locations where it took place.
