Chapter XIV: Section 1728: s. No boy under sixteen years of age shall, in any city

of the first class, distribute, sell or expose or offer for sale any newspapers, magazines or periodicals in any street or public place or work as a bootblack, or in any other street or public trade or sell or offer for sale or distribute any hand bills or other articles, unless he complies with all the legal requirements concerning school attendance, and unless a permit and badge, as hereinafter provided, shall have been issued to him by the state factory inspector. No such permit and badge shall be issued until the officer issuing the same shall have received an application in writing therefor, signed by the parent or guardian or other person having the custody of the child, desiring such permit and badge, and until such officer shall have received, examined and placed on file the written statement of the principal or chief executive officer of the public, private or parochial school, which the said child is attending, stating that such child is an attendant at such school with the grade such child shall have attained, and provided that no such permit and badge shall be issued, unless such officer issuing it is satisfied that such child is mentally and physically able to do such work besides his regular school work as required by law.

SECTION 1728 t. Before any such permit is issued, the state factory inspector shall demand and be furnished with proof of such child's age by the production of a verified baptismal certificate or a duly attested birth certificate, or, in case such certificates cannot be secured, by the record of age stated in the first school enrollment of such child. Whenever it appears that a permit was obtained by wrong or false statements as to any child's age, the officer who granted such permit shall forthwith revoke the same. After having received, examined and placed on file such papers, the officer shall issue to the child a permit and badge. The principal or chief executive officer of schools, in which children under fourteen years of age are pupils, shall keep a complete list of all children in their school to whom a permit and badge has been issued, as herein provided.
