Here is the Grand Opening ad from the weekly Jeffersonian Democrat of Brookville, July 3, 1952 edition. It matches the drive-in’s current claim that it first opened that year.
It’s very unlikely that whatever copyright might exist on this advertisement would have been renewed, but don’t take my word for it. Of course, I have no interest or claim on any existing copyright, so use at your own risk. I have uploaded it here for the fair use scholarly purpose of establishing the opening date for this drive-in.
