This international bestseller is an endearing illustrated chapter book about an African giraffe and his pen pal, a penguin. It's hard to imagine someone you've never seen... Giraffe is bored, as usual. He'd love a friend to share things with. So he writes a letter and sends it as far as possible across the other side of the horizon. There he finds a pen pal-Penguin. Giraffe knows nothing about penguins and his letters are full of questions. What does a penguin look like? Where is a penguin's neck? And so the letters begin to fly from horizon to horizon. Yours Sincerely, Giraffe is a funny tale of mistaken assumptions and friendship.
