​​​​ I will display a copy of the federal license and state permit at my booth at the gun show.

​​​​ I have never been convicted of illegal activity involving firearms.

​​​​ I will ensure that all firearms and frames or receivers of firearms sold by me at the gun show will be preceded by a background check of the purchaser and comply with the three-day waiting period required in state law.

​​​​ I will display and offer for sale or transfer ammunition in compliance with any applicable state or federal law.
