It's cool erri.

I've found yet another nice original 1976 release poster done by Averardo Ciriello:

It was a big (140 x 198 cm) two-panel poster, which means that it was printed in 2 sections. The same art that was used for the smaller ones...

unfortunately I haven't found it uncensored and in better quality. :(

Here you are also able to see the full artwork on the other one posted in this thread: http://www.film.tv.it/film/9117/l-uomo-che-fugga-dal-futuro/foto/2/ Don't know if that one was done by Ciriello though. Probably video poster/cover.
