First I read a rather apocalyptic article about oil running out (with this near-ecstatic gem of a closing line "Years from now, when we hear singing at all, we will hear ourselves, and we will sing with our whole hearts."). Then I saw this 1930s Italian advert for a long-gone petrol brand called Lampo (flash/lightning). Some things just drive a wry smile.
