I remember this hippo from the Childcraft book on art from when I was just a sprout, many many years ago. I've always thought it was beautiful.
In fact, now that I think about it, there's a children's book about it that we got from the library when my kids were kids: The Blue Faience Hippopotamus. Link.
Aw, these are so cute! The hippo on the left reminds me of The Blue Faience Hippopotamus, one of my favorite books as kid and I love how joyful and prancing the gold/burgundy fellow is.
