My book Stumper is a children’s book that I predict comes from the 90s (even 80s maybe). I had it read to me everyday when I was a kid (I’m 22 now).
I have no idea what it’s called, but the cover depicts night time (Navy blue) with a restaurant illustration! I remember the book being rather large and rectangle (long). To give you a visualization, it sort of resembles Van Gogh's “Cafe Terrace at Night” painting!
The book follows a brother and a sister who run amuck through the restaurant - they run through the chefs kitchen and hide under the tables. They also do a lot of magic tricks. I vividly remember a white rabbit in a hat and the extending handkerchiefs!
The girl has black hair in a short haircut, and I can’t remember what the brother looks like.
I suspect that it’s not a popular childrens book as I’ve looked at countless lists and it’s never been there!
If you can find this book, I will be beyond happy. I have literally been searching for it for YEARS!
