I HAD to take it, cause two weeks before I took (of course you do as a 'hamburger jung') a, no, the BIG harbour tour in Shanghai. Best place for fresh air there, btw.

link is essentially a Keystone Wizard plus an integrated electronic flash (another difference is you can lock the shutter to not accidentally hit it. clever.), rebranded for a big german catalogue company. As far as I know it was only available there. Mentioned link claims it was even produced by Polaroid - who knows. It is not known much about the (or a) connection between Keystone and Polaroid.
