Exactly. Boxes full of them. And I still have some large-format 2 1/4 x 2 1/4 inch transparencies. I have a viewer for those but the projector is long gone. When those big suckers were projected it was like HD compared to 35mm slides. I took them with a Yashica, a very good knock-off of the German-made (and expensive) Rolleiflex.
