Cards illustrated with coloured cartoons, 34 of 35, from a series concerning various diseases and their prevention by childhood vaccination, for use in public health campaigns in Colombia, produced in Colombia in association with UNICEF, 1980-1983. This particular card depicts a yellow bacterium that is in the shape of the letter 'D'. The words 'D de Difteria' are written in bubble writing above the image. The background to the card is bright blue.

The cards are illustrated with cartoons to campaign for childhood vaccination in Colombia, South America. They promote vaccination against five of the main diseases responsible for childhood deaths: measles, tetanus, diphtheria, whooping cough, and polio. They also explain the expected reactions to vaccination and the medical treatment needed if one of these diseases is contracted.

The cards were produced in association with the UNICEF, (United Nations International Children's Fund). The charity aims to vaccinate all children in the developing world against the six main childhood disease killers (the sixth being tuberculosis, which had already received widespread coverage in Colombia).
