Sticker art (also known as sticker bombing, sticker slapping, slap tagging, and sticker tagging) is a form of street art in which an image or message is publicly displayed using stickers.
These stickers may promote a political agenda, comment on a policy or issue, or comprise a subcategory of graffiti.
Sticker artists use a variety of label types, including inexpensively purchased and free stickers, such as the United States Postal Service's Label 228 or name tag.
