Many of the Mexican artists of the post-Revolutionary decades accepted that the government endorsement of using art to educate the largely uneducated public was a tacit approval to produce art heavily reflecting communist ideology. Revolutionary themes and communism combined in many works of the period. But the 1930s were turbulent times, Mexican communists were sometimes embraced and sometimes not embraced by their US and Soviet counterparts. Brenner was a sympathizer, like others of Mexican "avant–garde", who were sometimes Communist Party members and sometimes not. In 1926 when the journal "New Masses" was launched, Brenner was classed as a fellow traveler, but not a party member.
