I don't have any pictures, but we line up a series of sterilite containers (with holes) for air and then have small sheets of glass that we lay over the tops so they cannot get out but people can see them clearly. Then we label with a paint pen on each one. It's not that fancy, haha, but we do have a display case as well.
As for bringing a personal pet, I used to do it with a few of my boas. Not my ball pythons. Depending on which vendor I was by usually. Haha.. for reasons.
