Eduardo Malta, who uses the pseudonym Papusse, was one of the first chief editors of the O Século-supplement Pim Pam Pum!, together with writer Augusto de Santa-Rita. Most of Malta's comics are based on scenarios by Santa-Rita (Pápim). These two artists were also the first to make a comic album for children: 'O mundo dos meus bonitos', which was published in 1920.
