Here's an interesting and quite-rare item!
A Sally thing from the USA. Usually Australia is the hotspot for "SatAm" type items, but this one is American. This is a pencil-topper/eraser. It's rather unusual for an eraser, being so detailed and fully 3D/figural. It is actually quite well sculpted too, as she has all her fingers, an out-reached arm, and details of her hair. The pencil fits into the block at her feet. You can see she fits onto this classic Sonic pencil.
Where could something like this have come from? The Luxor Hotel of all places, in Las Vegas. For kids, they had a prize machine in the 1990s, where you could win a variety of Sonic goods. This pencil & topper was among the selection.
