The Imperial Mark 27 is a nifty plastic camera made by the Herbert
George Co. of Chicago, probably in the 1950s. It's called a
"3-way flash camera" on the box, and a "3-in-1 hideaway
flash camera" on the instructions. Apparently, this is because
the camera can:
- Take color slides
- Take color snapshots
- Take black & white snapshots
There you have it! Three!
I'm not sure why you're supposed to close the flash door when not using the flash, but the Herbert George Co. also made the "Official Boy Scout 3-Way Camera (same camera as this one, but with a Boy Scout logo on it), and that one doesn't say you have to close the flash door!
For 12 exposures on 127 film.
