thanks for the message - then we wait for Jonas Richter and his expertise.
I did take a look into the book https://drw-www.adw.uni-heidelberg.de/d ... blaettere= as you proposed

There it might be of interest to understand the complete book, not only page 86.
It becomes very clear that the author of the book of 1933 did see the original documents, and that the well-known Nördlingen/karneffel-citation on page 86 refers to a document written down in 1510.
The book furthermore has a register, and hence, you find on page 663 not only a reference to p.86, but also a second reference w.r.t. cards on p.128 (which is wrong, it is page 129 you have to consult): this second text was written down in 1476, but it does not mention any special name of a card game (as the reference on p.86: bossen in thurn, karneffel, hundert und ains), only playing cards in general. Hence, there is an earlier reference to cards 1476, but not 1426/27/32 or so..
