The auction says ORIGINAL, The question is, define original.
If original means first issue or the like, the answer is NO
If original means that they are not reproductions the I would say YES.

Since the autographs appear not to be on the photo but seem to be cut signatures, I would be a little more than suspect about them especially since they all seem to be signed on the same type of material.
If you had either a photo or document with all 4 signatures, why would you cut them?
