Curious George's Opposites — H.A. Rey

“Very nice…a series of scenes featuring the mischievous monkey that illustrate concepts, such as up, down; in front, behind; dry, wet; and so forth.” -- Publishers Weekly
 
Riding forward and backward on his bicycle and letting pigs in and out of their pen, George, in his typical inquisitive manner, explores opposites in this simple, humorous book featuring classic illustrations from the original series by H.A. Rey and Margret Rey and starring the “adorable but trouble-making” monkey beloved by generations of children (Forbes).
