I found this children's book in Omaha last year, intrigued by the line illustrations. Written by Louis MacNeice, a successful Irish poet and playwright, The Penny That Rolled Away { The SixPence That Rolled Away in Europe} was his only writing for children.
Once upon a time, it starts, there was a half dollar and he married a quarter and they had three children - a dime, a nickel and a penny. An adventure ensues.
The illustrations by Marvin Bilek are kind of whimsical and wonderfully detailed. I want to find some more of his work.
