Bad assumption. Things that were actually registered even if there was
no notice, or published with a copyright notice would still be
protected under U.S. copyright.
Depending on when. If it was published without notice, the key question
is whether publication occurred before Jan 1, 1978, or after. After,
notice does not matter; before, lack of notice means no copyright.
Indeed. Apple even screwed up on this with their iconic rainbow apple
logo. I discovered this while researching the history of the logo while
doing image work on Wikipedia / Wikimedia Commons many years ago. It is
still a trademark, but the image is public domain because it was published
before 1978 with no notice.
