Each privilege license issued shall be kept posted in a conspicuous part of the place of business of the person to whom such license has been issued where the business carried on has a permanent location, and if the business is such that the license cannot be so posted, then the licensee shall have such license in his actual possession at the time of carrying on such business or doing the act named. In all cases where the question arises as to whether a privilege license has been procured, the license or record thereof, if in existence, shall be the only evidence of payment.
When a proper holder of a privilege license to engage in any business at any definite location in a county desires to remove same to another location in the same county, the tax collector shall upon proper application in writing by the licensee, grant to such person the right to make such move, and shall endorse upon the said license his approval of the change in location.
