The most interesting was an 1929 ad for Just Another Blonde, which ran in the Murray Eagle. The film was being screened, for one day only, on Sunday, May 19th at the Gem Theatre. (The ad described the film as "a thrill packed story of a Romance that was made in heaven - and remade on Earth!") Just Another Blonde, a silent film, was first released in December of 1926. It's intertesting that it was still being screened some two-and-one-half years later, and once talkies had come arrived.
Along with the Utah Digital Newspapers project, I have also looked through similar efforts, including the Colorado Historic Newspaper Collection and the Missouri Newspaper Archive.
