Generally, representations, designs, or mottoes, or combinations of these, used to signify an individual, a group, or sometimes a commercial concern, and usually intended to convey a sense of lineage or quality. For devices that are symbol- or picture based, designed to identify at a glance a product, company, or organization, and often used as trademarks, see "logos." For devices that specifically identify a person or object as belonging to a group or organization, sometimes denoting rank or office, see "insignia."
