Vienna Philharmonic Program from First American Tour
The Vienna Philharmonic performed in Burlington, VT on 1 December 1956 as part of their first tour of the US. Almost 40 members of the orchestra (including Willi Boskovsky) signed the cover of a program and presented it to Richard Stoehr with the German inscription: “For our dear teacher and master, to remember his students.”
The program is also signed (above and to the right of the eagle) by Helmut Wobisch, a well-known Nazi member of the orchestra whose activities in that regard are discussed in this article in the Guardian:
