Oval stickers are stickers that come oval, rather than your typical circular one. They are quite versatile and can be used for a variety of purposes, both personal and commercial. This bumper sticker design is widely popular and is often called “euro stickers” or “international stickers”.
In the early 20th century, white oval stickers featuring black letters emerged in Europe. Vehicles crossing borders are mandated to display one of these stickers, indicating their country of registration.
