I found this in my files: A 'collectors certificate' from Mr. Friedrich Mueller of the "Japan Art Gallery" in Frankfurt, Germany featuring my "Gletscherzeichnung" (Glacier Drawing) from 1994. It shows the drawing, the signature, dates and all other specifications. This is how it's properly done. "Provenance"
*It is also the only photo of this piece.
Below: an enlargement of "Gletscherzeichnung" from the certificate.
