The contract and permit authorized by this chapter must be made in duplicate. One must be in the possession of the governing body or fair board and the other in the possession of the manager of such carnival, and in either case, upon request of an officer or citizen, must be produced and shown. Refusal to show the same to one asking to see it is presumptive evidence that such carnival is being operated without such contract or permit.
