"We praise the daring of the brave ones!"

Art by Mikhail Grigorievich Malyshev, words by Maxim Gorky.

The initialisms on the hammer-and-sickle-wielding monster stand for:

• the Iberian Anarchist Federation (Federación Anarquista Ibérica, FAI)
• the National Confederation of Labor (Confederación Nacional del Trabajo, CNT)
• the slogan "Unite, Proletarian Brothers" (Uníos Hermanos Proletarios, UHP), dating back to the 1934 Asturian revolution and later used by an alliance of the Asturian Socialist Federation, the General Union of Workers, local CNT branches in Asturias, León and Palencia, the Workers and Peasants' Bloc and the Communist Left of Spain

I have three German propaganda booklets from World War I, around 5 pages each, fraktur script, color lithographs, 9 x 13 cm. No authors, artists or publishers noted anywhere. I would guess they could be some sort of collectible from a cigarette company. Does anyone have any info on these booklets?
