curbstoning
 n.— «The measure regulates realty dealers by prohibiting any one from selling land as agents for another without securing a certificate of license.…The passage of this act would effectually abolish “curbstoning,” and much of the unreliable tactics employed by irresponsible real estate sharks.» —“Worth Realty Measure” Modesto Evening News (California) Mar. 27, 1913.
