Volts, joules, watts, kilowatts, jigawatts—we get units of energy mixed up. But this cover is electric however you measure it. William (undoubtedly a pseudonym) Bentley’s 1964 thriller Amore a 5000 volts is another example of Edizioni MA-GA’s Il Cerchio Rosso series, which has produced consistently excellent cover art. This one is uinsigned, but probably by Franco Picchioni. Click the keywords below and you’ll see what we mean.
Edit: the art is confirmed by Picchioni, plus we found the original.
