On “Read Across America Day,” which is celebrated on Dr. Seuss’ birthday, Dr. Seuss Enterprises announced that they will stop selling six of his books, because they contain outdated and “hurtful” depictions of Asians and Africans. The most recognizable of those six are 1937’s “And to Think That I Saw It on Mulberry Street” and 1950’s “If I Ran the Zoo”.

Now of course, these books are now selling like crazy online. Some people are already offering to sell their copies for thousand of dollars!
