After doing some research, with the help from numerous websites including our own HHN history page, I believe I may be able to answer your question! The eye does look similar to the 1997 HHN Orlando theme poster, and HHN Hollywood first started in 1997. But, that year at HHN Orlando there was no feature of Psycho. Continuing, at HHN Hollywood they feature the Terror Tram, which goes past the set of the horror classic Psycho. So to my conclusion, the shirt probably originated from a gift shop at the end of the tour, which featured the HHN Orlando eye logo with Pyscho mixed in. Hope this answers your question!
