What you're about to see is not a product of Elka, but rather a dog whose identity (and whose owner's identity) will remain protected.
The book in question, for it was a book, was from 1929, and was essentially sheet music with cardboard covers, on how to play the Ukelele.
I do apologize for the quality of the photos; first, I took them with my phone, and second, I couldn't remove what was left of the book from the manilla envelope to do so.
It is now, quite literally, a pile of shredded pages. Originally, the book cost 50 cents. There's been some inflation, though, so the owner will pay a bit more than that. Not too much. But I do hope this owner is sure to place books out of doggie reach in the future!
