We shared some of these PSAs a few years back, but I think the world can always stand to hear a little more about brother- and sisterhood.
Back in the 1950s, DC Comics regularly ran public service ads for
National Social Welfare Assembly promoting harmony between people of
difference races, creeds and nationality. A selection appears below.
Many of these ads
promoted National Brotherhood Week, which was sponsored by the National Conference for Community and Justice (NCCJ) (formerly known as the
National Conference of Christians and Jews) and was observed during the third week of February from the 1940s to the 1980s.
The NCCJ is "dedicated to fighting bias, bigotry, and racism and promoting
understanding and respect among all races, religions, and cultures
through education, advocacy, and conflict resolution."
