I can't tell you anything definitive from a posted scan, but it is possible for an original photo to have an original tag and a later stamp (and no other noticeable stamps), and I've seen it a few times. For example, when UPI acquired the International News photo archives, they sometimes added their modern stamp to old International News photos.

A few times I have seen original paper tags on modern reprints (meaning, legitimate reprints made by news services not fakes), but it was more than obvious they had been removed and reattached. Sometimes scotch taped on. The old paper tags are delicate and originally glued to the photos, and it would be hard to remove and reattach one without messing it up. If you pull off an old tag, usually part of the tag will remain attached to the photo. That's why you see brown paper remnants on the backs of many old news photos.
