Enzo Suma, a naturalist guide, has always picked up rubbish during his walks along Carovigno beach, a stretch of coastline lapped by clear blue waters close to his home in Salento, an area of Puglia in the heel of Italy’s boot.
During one walk, Suma, 44, spotted a washed-up bottle of Ambre Solaire sunscreen. He was about to throw it away when he noticed something unusual: the price printed on the bottle was in lire, meaning it must have been produced before the euro replaced the lira in Italy.
