They established the Shamir Brothers Studio on Rothschild Boulevard in Tel Aviv and began to design posters.

Whereas Franz Kraus, the Austrian graphic designer who arrived in Eretz Israel a year before the Shamirs, adhered to a uniform type style, the brothers sought typography that they felt expressed the subject matter.

The Shamir brothers, enthusiastic about the establishment of the Jewish state, undertook to formalize and actualize the visual symbols of Israeli sovereignty and independence.

Their posters, other advertisements, and logos from 1935 to the close of their studio in 1974—rendered for the lottery, marketing fairs, land settlement, support of the army, food rationing, anti-black-market drives, and other nationalistic efforts—express a hyped Communist attitude, but not extreme or dour as in the propaganda of Bolshevik Russia.
