This 1990 Russian reworking of the Star Wars: A New Hope poster is a little different from the Western versions.
I'm assuming the object at the top is the Death Star but who's the handsome devil at the bottom of the frame?
It may not be anyone... consider this other Russian poster for Star Wars.
This is quite literally a "space cowboy". I mean one could argue it is supposed to be a depiction of Han Solo, but how could you prove it?
Here is another for Return of the Jedi that I have no idea what is going on...
Consider the excerpt from the answer given by @user931:
At that time, local artists produced posters for foreign movies without any knowledge of the films, which led to some unique designs.
In the end I think you have to take the poster at face value, in that they are "generic" depictions of "space things".
This seems to be a trend with foreign movie posters from various countries...
From this page (which has this image embedded):
In 1990, Star Wars was finally released in Russia. At that time, local artists produced posters for foreign movies without any knowledge of the films, which led to some unique designs. This rare poster describes the movie as a “galactic Western” and features an imaginary image by Yury Bokser dominated by an unusual depiction of what could be Jabba the Hut and the Death Star with stars shooting out from the centre.
