incorporates a spear and shield – symbolising the historical and ongoing struggle, armed and otherwise, against colonialism and racial oppression – and a wheel, which is borrowed from the 1955 Congress of the People campaign and therefore symbolises a united and non-racial movement for freedom and equality. The logo uses the same colours as the ANC flag, which comprises three horizontal stripes of equal width in black, green and gold. The black symbolises the native people of South Africa; the green represents the land of South Africa; and the gold represents the country's mineral and other natural wealth. The black, green and gold tricolour also appeared on the flag of the KwaZulu bantustan and appears on the flag of the ANC's rival, the IFP; and all three colours appear in the post-apartheid South African national flag.

In addition, since 1972, it has been traditional for the ANC president to publish annually a so-called January 8 Statement: a reflective letter sent to members on 8 January, the anniversary of the organisation's founding. In earlier years, the ANC published a range of periodicals, the most important of which was the monthly journal Sechaba (1967–1990), printed in the German Democratic Republic and banned by the apartheid government. The ANC's Radio Freedom also gained a wide audience during apartheid.

It is also common for meetings to sing so-called struggle songs, which were sung during anti-apartheid meetings and in MK camps. In the case of at least two of these songs – Dubula ibhunu and Umshini wami – this has caused controversy in recent years.
