In addition to the ones shown above I also have a cut out as shown below. Since Ars Medici also had envelopes with the same overprints as wrappers it is not possible to tell if this was a newspaper wrapper or an envelope.
So I'm waiting for another one to turn up (I've been patiently waiting since November 2006).
