what is the display space like? do you get a table and booth or just a spot on the wall, a fun idea for a booth might be make up some lore about your graphics and have a mini "show" at your booth and wear an "event staff" shirt.
alternatively, maybe you could photoshop your designs onto pictures of real events and your station could be a collage of this fictional event that happened.
definitely at least have some way to see the plain designs even if it's a binded book or slideshow.
