Yes, under US copyright law, an unpublished image is copyrighted for 120 years, unless you know who the author was, in which case it is copyrighted for 70 years after that person's death. So, for example, an unpublished image created in 1890 by a person who died in 1943 would still be copyrighted.
On the other hand, if the image was published, then different rules apply, and if it was authored by a foreign citizen in a foreign country, different rules may apply.
An image published 120 years ago by a US citizen in the USA, even with a proper copyright notice and renewal or registration would have expired. As a rule of thumb, anything published prior to 1923 in the USA is public domain. Again, anything UNPUBLISHED could still be copyrighted for well over 120 years.
