Mr. Popper's Penguins, a set on Flickr.On one of our after-school stops at the public library, I recently scored a 25 cent copy of Mr. Popper's Penguins in the used book sale section. What a treasure hidden amongst all the trash! How I did not already have a copy of this classic, I'm not really sure. But this one was so much better than a fresh new one. Hardback, library dust-cover, and old (I forgot to check the printing!), the paper is thick and slightly yellow instead of bright white. And best of all, the illustrations are sublime. I had to snap a few pix to share. I didn't take any of the ending so you don't have to worry about spoiler alerts. Such great fun with penguins, it has been a delight to read and enjoy!
