Blue Belle My Little Pony 1984 McDonald's Bookmark
The bookmark functions more as a paperclip. It has a clip at the top that can attach to paper or a book, but the pony itself is three-dimensional so it wouldn't fit inside a book.
Blue Belle's symbol is worn off and there's also a small chip on the back, as shown in the photos.
The back of the bookmark is marked "1984 Hasbro."Condition: Used, vintage
