All the articles are listed bibliographically and wherever possible illustrated with a photo. We refer to as exaxt a data as possible. If you should possess information, which we do not know (e.g. the year of publication of an acticle), do inform us with the source specification. After the items are sold, most of them are listed with a photo in our database (archive). Thus the data is available later on. For better indication the article numbers are only assigned once.
