ICA Stereolette
Another contender from ICA for the worlds sexiest camera I have to confess that I know very little else. Made in Germany there were a number of models, a 610 and 611 made between 1912-1926 and a 620 Cupido from 1912. ICA were one of the first companies to use Carl Zeiss for their lenses.
