Image quality

Please pay attention to the fact that we need images of high quality (4 MB at the maximum, no zip file) to identify your furniture. It is very important that stamps and product labeling (e.g. paper marks or stamped marks) are shown in your photographs. These signs are mostly situated at the seat frame or underneath the furniture. Furthermore, the provided images must show the status quo of the furniture; please don't edit them.

We would like to point out that we survey your furniture according to the best knowledge of the Thonet history; nevertheless, all information is supplied without liability.
