This catalogue entry appears to refer to Giuseppe Valdengo (1914-2007), the Italian baritone, here preserved under the misspelled product-tag form “Valdegno.”

In the Pristine catalogue this duplicate-form page is attached to Toscanini’s 1949 Aida.

Valdengo was closely associated with Toscanini’s late Verdi recordings and is represented more fully under the standard Giuseppe Valdengo spelling.

This page is best understood as a duplicate tag marker, useful for keeping older catalogue spellings intelligible.
