I think the most famous example of the "with notice" thing is the original Night of the Living Dead, which is public domain by accident.
To quoth Wikipedia:
Night of the Living Dead lapsed into the public domain because the original theatrical distributor, the Walter Reade Organization, neglected to place a copyright notice on the prints. In 1968, United States copyright law required a proper notice for a work to maintain a copyright. Image Ten displayed such a notice on the title frames of the film beneath the original title, Night of the Flesh Eaters. The distributor removed the statement when it changed the title.[82] According to George Romero, Walter Reade "ripped us off."[83]
