Penny House is a unique combination of birthday fun and sly commentary about"how much stuff" we all have. Mr. Alfred C. Dunphee wakes up on the morning of his 100th birthday and says to his dog Pup,"It's time to make some changes. You are only 100 once!" The book follows the changes he makes during his birthday week and finally, after ridding himself of half of his "collections" he covers his house with his penny collection. Thus, Penny House.
