The group formed in 1933 at the house of Leopoldo Méndez as a convergence point for progressive literary voices supplemented by powerful imagery in protest against Fascist aggression in Spain, and in support of the underprivileged. Its main publication was Frente a Frente, Front to Front with images by Pablo Higgins, among others. John Heartfield's photo-montages were used for several covers. The group was disbanded in 1937, the year in which TGP was launched.
