Arthur's April Fool

Arthur's April Fool is the seventh book in the Arthur Adventure series. It was written and illustrated by Marc Brown and published by Little, Brown and Company on March 30, 1983. The re-illustrated cover that shows what Arthur and his friends look like today has a very similar pose to the first edition, except with his mouth open and cards inside the top hat and in his sleeve. The re-illustrated cover edition also included special-edition stickers.
