I have two records purporting to contain Marconi's voice.
One is an "On the NBC record in which, after a too long intro, there is a
brief message va shortwave of a gruff-voiced man.
The other, about 3 miunutes plus intro, is on "General Voices from History,"
CS-051314, in which a person with an English accent, no trace of an Italian
one, recites his accomplishments.
I'm suspicious of the second item. Anyone have data on these?
