I found a decent amount of sizes intended for pez collectors, I researched some of the prices of vintage pez, and they top off somewhere in the 300 dollar range.
There is even a pezwiki.
The audience that this is geared to is the collectors of these little pieces of plastic. They would have been first introduced to these items as kids. I don't think there has ever been a child who has not owned a pez dispenser. From what I can figure most people are interested in these for nostalgia reasons, and they are a small easy thing to collect... till you get into the ones that are 50 years and older. I think everyone likes the pez dispensers because it brings back a feeling of childhood, memories of getting them on Halloween or on Christmas, or just begging your parents to get them one of their favorite characters. Its a toy and candy, you cant rope kids in any harder. I think that an exhibit about this would bring people in because of a general knowledge of the artifacts, and the people who collect (or Pez-Heads) are serious about their hobby.
