or giving any example of his or her skill in knowledge of boxing

shall be paid or given, either directly or indirectly, to any
contestant in an amateur boxing contest.
18752.  Unless the written permission of the commission is first
obtained, it is a misdemeanor for any promoter to pay or cause to be

manager and amateur boxer in traveling to and from their respective
residences to the boxing contest in an amount to be determined by the
commission.
