PhotoCD seemed like a pretty half-assed effort and there wasn't really a market for it. There were PhotoCD players but no one really wanted to view their images on a TV. So great, you've digitized your photo, now what? People just weren't sharing their images digitally yet. But anyway, my dad tried to sell them in his shop, and I transferred 100 of my favorite images at the time to PhotoCD in 1993. Here's a few:

Probably shot on Kodak Gold 100 color negative with a Nikon FE2. Gosh I suddenly miss the smell of film.
