Props such as the one pictured to the right are very expensive and can sell for up to $310.00 on sites such as eBay. Props such as these are often used as Halloween decorations that are added to a scary scene for trick-or-treaters or simply just used for common everyday alien and UFO related themes. One of the other alien related decorations similar to that of the common Halloween props is the alien wall plaque manufactured by Design Toscano which features an alien head with two hands, making the alien appear to be coming through the wall.
Some of the most famous forms of prop-like alien decorations are based on the well known grey aliens, while other forms of decor such as inflatable balloons are based mainly on the green aliens dubbed "little green men".
