I was just about to say this. I love The Tingler. It's such a good concept and all the marketing gimmick stuff like the Percepto! vibrating seats was great. Here's an article with lots of fun facts and those brilliant posters.

At one cinema, where The Nun’s Story was screening during the day, and The Tingler after-hours, the projectionist accidentally switched on Percepto! during a poignant moment in the film, causing a bit of a ruckus.

Also Vincent Price does LSD in it. What I didn't know before reading the article is its the first LSD trip in a Hollywood film.
