Its funny they write that this objects were found in a castle near Switzerland
(where? In Austria, Liechtenstein, Germany, Italy, or France)
and that times (1928) it is most convincable that such pitch garlands were not shown in European museums or collections, as they were not so decorative like metallic arms and armour.
