Alfred Hofmann also designed a music related medal in 1949 but I don't know anything
about his other medal works yet.

Depending on how the piece is signed, it could be easy to mis-attribute an item as
there was also an Adolph Hofmann who designed Austrian Coins, Medals and Tokens
and with Hofmann being a common name there may be others.
