We have a 36"x60" sign we hang up behind us at Festivals. It has our Club name, city, brief description of us ("A Collection of Zymologists"), and our website. I used to have an email sign up sheet. But, I don't do that anymore because about a month later, most want to be removed. So, if someone is really interested, I would collect their name and email address. I would also direct them to our website, and facebook page. Hope this helps.
