This Aliens inspired metal sign, features the screen as seen in the special edition version of Aliens, where the Colonial Marines set up the UA 571-C sentry guns.
Originally cut from the theatrical release to save on time in the movie, the automated sentry guns have become a bit of a cult hit over the years amongst die hard Xenomorph fans, and so here is the exact view as seen in the movie!
This sign is available in 3 standard sizes:
305mm x 200mm (A4)
420mm x 297mm (A3)
594mm x 420mm (A2)
