"Samuel Roth, who ran a literary business in New York, was convicted under a federal statute criminalizing the sending of "obscene, lewd, lascivious or filthy" materials through the mail for advertising and selling a publication called American Aphrodite, ("A Quarterly for the Fancy-Free") containing literary erotica and nude photography. David Alberts, who ran a mail-order business from Los Angeles, was convicted under a California statute for publishing pictures of "nude and scantily-clad women." The Court granted a writ of certiorari and affirmed both convictions."
