On October 6, 2022, Deutsche Post issued a postal stationery on the occasion of the Ulm Stamp Fair from October 27 to 29, 2022. The QR code was missing on the imprinted stamp. Therefore, the stamp fair postal stationery was withdrawn from sale. A corrected edition was available from October 19, 2022 onwards.

In addition, the stamp fair postal stationery with QR code was available in two variants. Obviously, in one part of the corrected edition, the QR code was printed "quickly" so that it was "improper" compared to the normal printing. In both cases, however, the code was readable.

The print run without QR code probably ranges between 1.000 and 1.500, the total print run between 13.000 and 16.000, the ratio "proper" to "improper" is assumed to be 1/3 to 2/3. Another peculiarity is the imprinted stamp, an image of the "Baden misprint", but in inverted form
