Ah much better, nice Mike.
Yep, they sure do look like they were sent to the newspapers, I dug mine out but I couldn't find Silent Running but I did have advertising press kit and mine are for the theaters (posters/daybill). I wonder if they ever had anything like I have for when SW was going to be released? I can't find any in the archive.
Here's some pic's I took so others can check it out.
Thunderbirds Are Go Pressbook 1966.
Journey to the Far Side of the Sun Advertising Publicity Promotion booklet 1969. This also has on the back page, 2 mail away orders for free commercials and radio spots.
Advertising Supplement 1969.
