I'm having problems trying to find out what I've got here - it looks like a colour trial but it has been through the postal system in Stuttgart.

Are colour trial collectable? Posthorns are a very popular set so I would think someone would find this interesting.

Most likely natural or chemical discoloration.

Here is another example of chemical treatment of a green stamp to create a yellow stamp.

Hi,

Sometimes green comes blue. Would have been nice on cover as single usage! (70 Pf rate)

Drbob, Plate flaw + Bahnpost Nice!
