Expo need brochure, wherever and whenever they are held the participant vendor need brochure. The printed brochure is really useful to communicate with people about our company, you can also add vision, mission and also product line up.
More detail about product that we sell is also good. Just like vini tankless who use brochure to help their sales promotion girl introduced their water heater product to potential customers.
Not all printed brochure was bad. Many of customers still love this kind, and reject digital type. This because they are more simple.
For the good sample of brochure design, you can take inspiration from vini site and hope your expo will be successful campaign.
