Crusader Rabbit, story adopted by Oscar Weigle, pictures by Athur Krusz (children's HC, 1958, condition is good except for separating clear plastic covering on the lower spine, $11, which is 1/3 the internet price.)
I was old enough to remember this series, at least vaguely.
Should rabbits eat carrots or cream puffs?
Will all Texas rabbits be sent to the North Pole?
Look for the answers to these questions in this book to be found on the top of the glass case, avail. 6/24.
