Signāls.

Note

Global Avantgarde Latvia 28; cf. Fraser L296-304. Left-leaning periodical published between 1928-1930. "The first two years of Signāls were characterized by plodding content but out-of-the-ordinary covers by different hands (...). By February 1929 the 24-year-old Andrejs Grigelis began designing covers, bringing some degree of mainstream European vanguard style to these issues." (Fraser).
