The picture might be a little bit deceiving as it kind of makes the smaller cameras look normal and the normal ones look big. For reference: That Pentax in the back is a normal-size camera. The Widelux in front of it is only a little bigger. With that basis, you can see that the Rollei 35S and the Fujica Mini are tiny.
I didn't ask about price. Probably more than I want to spend anyway.
