What types of products are covered under retail cigarette and tobacco licenses?

I have obtained a cigar license in Maryland through my business, House of Time, Inc. I was not sent any type of license to display. The companies I buy cigars from are asking me for a copy of my license. I do not have one. My license number is: 10751. This number I was given over the phone. Where can I get proof of my license to send to these companies? Please reply through my email. Thank you, Brenda McCabe
