Graphics events

Hi guys, I’m new on this forum. My name is Andrew and I’m a graphic designer for a couple of years.
Recently I’ve been invited to a Event Graphics by a friend of mine that works on the company who organized the event, I’ve never been to an event like this.
Anyone participated, what’s the purpose, graphic designers show their work?

Thank you in advance for your help.

PS: The event is on 1st of August.
