Browsing around Etsy, the "online marketplace for buying & selling all things handmade," I happily stumbled across these decorative birdhouses made out of Little Golden Books. (I wonder how many books one would need to make a chicken coop...) Little Acorn Products is the shop that creates and sells them. Do you recognize Scuffy the Tugboat, above? How about the Poky Little Puppy?
I just started reading the illustration-rich Golden Legacy (Golden Books, 2007), by children's book historian Leonard Marcus, and look forward to finding out "How Golden Books Won Children's Hearts, Changed Publishing Forever, and Became an American Icon Along the Way." I doubt there's any mention of birdhouses, which perhaps constitute a new chapter for the sturdy books.
