Back in 1949 my sister and I were given our first cameras - matching Kodak Baby Brownies:
These used 127 film and took 8 rectangular pictures. The processors normally contact-printed the film and gave a little yellow booklet with the photos clipped in, perforated so you could tear them out as wanted.
Of course they used a simple meniscus lens, but compensated a bit by having a curved film "plane" to keep the sides more in focus. (Curved sensors aren't really new.) Curving the film like that also kept it from buckling and made it more stable.
Of course, fixed focus, fixed aperture, fixed shutter speed, no flash - so outdoors shots only.
Yet we sure enjoyed the pictures we got from these.
The first films I developed were also 127, but from a later Holiday Flash (I think) Brownie. Loaded film into a Kodak plastic tank with a plastic ribbon to keep layers separate, using a guest-room closet for a "changing bag", and developed in Microdol-X. Then contact printed.
I found this one on eBay, and then searched for 127 film, which has largely disappeared in the last couple of years. I got a few rolls (B&W) from Japan, and each roll cost a lot more than the camera.
I'll try it out one of these days.
I also have a 1915 Kodak Vest-Pocket Autographic folding camera that is also 127. If I can fix the bellows leaks I'll try that also. And I have inherited two similar folding Autographics that take 120 film, so I'll try one of those also.
