This wall plaque in the historical old center of St. Gallen (near the intersection of Marktgasse and Speisergasse) shows Hans Varnbüler as the first recorded owner of the house known as the Haus zum Tiger. (Houses then did not have numbers, but had names instead). (Scroll down for a close-up photo below).
A closer view, showing Hans Varnbüler as the owner (Besitzer) in 1429.
