Alberto Solsona drew the fantastic and colorful series 'Agar-agar' for horror magazine Drácula in 1971. He shared the pages of this innovative periodical with such famous artists as Esteban Maroto, Enric Sió and Josep M. Beá. His style was reminiscent of pop art. 'Agar-agar' was written by Sadko. Around the same year, Solsona also contributed his work to Strong. For this kid-oriented weekly he turned out the series 'Arturito King' and 'Cartulino'. The imaginative daydreams of 'Cartulino' were written by Miguel Agustí.
