Abstract: An advertising unit includes a container and a flat divider dividing the container into two compartments. The divider is separate from the container and unable to support itself in an upright orientation. The divider includes an advertising display. A comestible product, such as soft-serve ice cream or frozen yogurt, is in the container on opposite sides of the divider and supports the divider in a generally upright position. Methods of advertising include placing advertising on the divider and providing the divider to a vendor of the comestible product. The advertising unit and advertising methods can be used to increase the impact of advertising by encouraging people consuming the product from the container to interact physically with the divider and creating a positive association between the advertising message and the experience of eating a desired comestible product.
