It shall be unlawful for any distributor of any book, magazine, periodical, or newspaper to refuse to sell to any dealer for his subsequent sale at retail any book, magazine, periodical, or newspaper if the distributor predicates his refusal to sell the publications desired solely upon the dealer's refusal to purchase from the distributor other books, magazines, periodicals, or newspapers not originally requested by the dealer.
