“ It is sent upon paying the license fee of fifty cents, provided of course the applicant is a member of the League. If you have not obtained your License, you ought to order it at once so as to have it framed and hanging up in your operating room when the time comes that you want your station to look well. Send a dollar, and we will send your Book, package of Official Message Blanks and your License all at the same time. ”
