A real UFO!
No, this is what we call in Dutch a "Spanjool" [español]. The stamps have been printed in 4-colour offset-litho. The ink of the colour - let's say the cyan [blue] - has been transferred via a rubber cylinder on to the paper. When the rubber cylinder has dust [or other tiny objects] on it this object will be pressed deeper in the rubber cylinder and around it there will be a moat that will not give ink! And that is what we see - the object and its moat! These things have nothing to do with a flaw on the form cylinders - one moment it is there on the rubber cylinder, the next moment it is gone [or moved on a bit ....]
