Offered here is the FIRST PRINTING (with the 77-21-0 NSS numbering) US one sheet poster with art by Tom Jung. Such was the success of the film, there were four different poster print runs for the A sheet in 1977 to meet demand from cinemas - all are considered to be first release although there are value differences between the runs. The first, and the most collectable, had NSS reference 77/21-0 with later 1977 runs marked 77/21. This version with NSS # 77/21-0 is the first printing. This one always commands a premium over the other versions. There are known reprints and/or reproductions of this poster. THIS IS NOT ONE OF THEM! This is guaranteed to be a genuine ORIGINAL MOVIE POSTER issued by the studio when the film was first released and meant for theatrical display.
