There is one listed on eBay at the moment:

http://cgi.ebay.com/Childrens-Storie...QQcmdZViewItem

Not 100% sure if it's the same book, but may be worth $3 plus shipping to find out! (Or maybe send a message to the seller and ask if the poem you are looking for is in the book).

There is also a copy listed here for $45 but the story is listed as "Quack said Joshua"
