The item in question is a specific type of costume accessory: a face covering depicting a cartoon character for the purpose of celebrating a holiday. This kind of product allows individuals to temporarily assume the appearance of a well-known animated figure, specifically during a seasonal festivity centered around disguise and role-play. One example is a yellow full-face covering to allow one to dress up as a simpson in halloween.
Such an item serves multiple functions. Beyond simple adornment, it provides a readily recognizable representation of a popular cultural icon. Moreover, its use can contribute to a sense of belonging within a group activity or themed event. Historical context would trace the rise of licensed character merchandise and the increasing prevalence of pop culture influences on holiday celebrations.
