It’s a children’s book for about 3rd or 4th graders. It’s thin, but it is a chapter book. The paperback version cover has a little girl on it with short hair and it’s red and yellow. The girl’s name might be in the title and is possibly Sally. She finds a bunny (pretty sure it’s a bunny) with wings and there may or may not be a circus. The book was older. She knows it from the early 1990’s, but it had like a 40’s or 50’s art style with simple line drawings with water colors. I saw some Golden Books that seemed promising, but she said those were all too young.
I’ve tried the below books and none of them were int.
The Country Bunny and the Little Gold Shoes
Felix and the Flying Suitcase
The Little Rabbit who Wanted Red Wings
My Little Rabbit Tale
Mr. Rabbit and the Lovely Present
