This listing is for the envelope only. Because it clearly lists banknotes (Scheine) with a denomination of 25 Pfennig, we are clearly dealing with a Notgeld envelope and not one for banknotes (which would have had at least a denomination of 1 Mark). Also, it must be for circulating Notgeld, given that this is by definition evidence of circulation, however it's certainly possible that there is overlap and/or less-than-perfect accuracy in categorizing various notes as either circulating or series Notgeld.
Uncataloged, only known example that I can find.
