Oliver Wendell Holmes, Jr., United States v. Thayer — Opinion of the Court
“ It appears to us no more open to doubt that the statute prohibits solicitation by writing as well as by spoken words. It forbids all persons to solicit 'in any manner whatever.' The purpose is wider than that of a notice prohibiting book peddling in a building. It is not, even primarily, to save employees from interruption or annoyance in their business. ”
