The Kodak Petite was a vest pocket 127 folding camera based off the ultra-popular Kodak Vest Pocket Model B camera and formed the heart of the Vanity Ensemble kit. It was a pretty standard issue camera for its type, though it did include an autographic pen (until about 1930) for impressing pertinent info into the very film itself.
As the 1920s came to a close, Kodak decided to dress the Petite up even further and appeal to a different portion of their market. So they created the Vanity Kodak Ensemble kit. It was the Kodak Petite with a new colorful covering (beige, green, or grey) and it came in a stylish folding case with vanity mirror, lipstick, and change purse. It is an interesting relic of the Roaring 20s. And while the lipstick probably has not aged terribly well and the silvered mirrors are likely tarnished, the camera itself will almost certainly still be working, just as it did 100 years ago.
Controls on the Kodak Petite are pretty simple. Most Petites have a doublet lens in a rotary shutter that has either T or I settings, with the former being a Time mode for long exposures and the latter an Instant mode that is likely around 1/50th of a second. Aperture is set via a wheel on the side of the shutter and presented four different aperture options, correspondingly numbered 1-4. Later models replaced this wheel with actual f-stops. An optical viewfinder allowed for composition and could be rotated 90 degrees for either portrait or landscape orientations. The frame size is 4x6.5cm for a total of eight exposures per roll of film.
