Need a date on the indy THX poster

Cant remember the date on this one, any quick help before I bury them in the cabinet and forget to inventory would be great.

If it's any help THX was founded in 1981, and Lucas first used it in 1983 I think for Return of the Jedi. I don't think "Raiders" got the THX soundtrack untill the dvd release which may have been 2008?

Raiders got a THX soundtrack for the 1999 VHS release.

I will have to dig mine out, I thought it only had Dolby until recently?

Mine is in storage in San Antonio, but I remember the THX lead in on the VHS.

Regardless, isn't the poster in question a theater advertisement?  I know I have some THX/Dolby posters from the early 90s... at least 1 is double-sided.  If my memory serves me, they looked more "modern" than this one. 

Could this poster be older (80's?) and they are simply using the Indy screen shot for illustrative purposes? 

[paul waines]

I don't think Lucas film would just use an illustration that was'nt in THX, it would seem a bit lax of them. If the poster was just to advertise them starting to use the proccess, why not a Return of the Jedi pic as that was their first film with THX sound.

Maybe it was put out around the time Temple of Doom was released.

I'm pretty sure I recall this poster in the 1980s sometime when THX was being pushed as the new sound system to be used by many productions. I definitely remember the ad campaign and seeing as I was living in Ohio at the time, it has to be sometime between 1983-1993, with an emphasis on 1983-86 time frame
