Movie 11 Poster
This is not exactly something new, but I found in a Chinese site a larger Image for the poster of the Detective Conan Movie 11, along with Detective Conan Calender Pages. The quality of it is not very great, but I guess it is good enough for the time being.
The poster has a semi-transparent picture of "Ran" to let you see the pirate ships behind her naked body, or that what seems. Of course, Conan's head is placed in such a way to prevent you from seeing what you should not see. The background seems to be deep under the water.
