Wyo. Stat. § 33-20-207
If complaint be made to the county clerk that any person, firm or corporation doing business in any county of this state is a transient merchant and such person, firm or corporation shall claim to be a permanent merchant, the county clerk shall require of such person, firm or corporation, and he or it shall furnish, a bond in the sum of five hundred dollars ($500.00), with surety or sureties to be approved by the county clerk. Such bond shall run to the county clerk as obligee and it shall secure the payment of the license in the event that such person, firm or corporation does not continue in the business which he or it is conducting in such county for a period of one (1) year from the time when such business was started; said bond shall also be for the protection of all persons, firms or corporations having claim or claims against the obligor arising out of said business. At the time of delivering such bond to the county clerk the obligor shall also deliver to the county clerk a duly executed instrument making the county clerk the agent of the obligor for the purpose of being served with process in the event of suit on such bond. Such merchant so complained against shall also furnish to the county clerk the affidavit required in W.S. 33-20-205 before advertising or holding out any goods, wares or merchandise as being sold as an insurance, bankrupt, railway wreck, insolvent, assignee, trustee, executor, administrator, receiver, syndicate, wholesale, manufacturer or closing out sale, or as a sale of any goods, wares or merchandise damaged by smoke, fire, water or otherwise. But after such merchant has been conducting the particular business in which he or it is engaged in such county for a period of one (1) year, such merchant shall be held to be a permanent merchant and the provisions of this act shall no longer be applicable to such merchant.
