MAO, Zedong.

Inquire · Offered by Peter Harrington

Sign celebrating Chinese aid to North Vietnam. A Cultural Revolution-era piece, the lettering on the rear face proclaiming "Long live Chairman Mao" and "Souvenir of the Campaign to Aid North Vietnam and Resist America." Its size suggests a dating of around early 1968, when the Mao cult was well established and propaganda objects were larger than in the early Cultural Revolution.
