This 1970s TV ad (done as a multi-image slide show) for Bank of Ireland makes you want to march right in and make a deposit, and then borrow it all back with interest. Multi-Image kodachrome shows are almost forgotten, but if you needed to project high definition images rapidly and coordinate a sound track, this is how it was done. I have some examples of my own on this channel. Click on the video 60s 70s NY Bus Party for a sample. (Yes this commercial is not pure multi-image as it has some zooms and animated titles added).
