Public Domain Comics: What You Can Read, Share and Reuse

Thousands of old comics are free for anyone to read, share, adapt and even sell. Each year more join them, as copyright runs out on works from nearly a century ago. For readers this is a treasure trove; for creators it is raw material.

The rules are not always obvious, though, and getting them wrong can be costly. This guide explains, for the United States, how comics enter the public domain, what the main traps are and how to use public domain work safely. It is not legal advice, and other countries have different rules.

What public domain means

A work in the public domain is no longer protected by copyright. Anyone may copy it, publish it, translate it, adapt it or use it in a new work, without permission or payment. That is how old novels are reprinted cheaply, and how classic stories are retold in new forms.

For comics, it means that old newspaper strips, comic books and magazine cartoons can be read freely online, collected in new editions, or used as material for new comics. Public domain status applies to the work itself, not necessarily to every later version of it. A modern edition may add new material, such as a restored colour scheme or an introduction, that is protected even when the original pages are not.

The 95-year rule

In the United States, works published long enough ago enter the public domain on 1 January, 95 years after publication. Works published in 1929 entered the public domain on 1 January 2025, and works from 1930 entered on 1 January 2026.

The rule produces an annual event that comics fans watch closely. In 2024 Steamboat Willie, the 1928 cartoon that marked Mickey Mouse's first appearance, entered the public domain. The first Popeye strip, printed in January 1929, followed with the works of that year.

The long freeze

For two decades, almost nothing entered the public domain in this way. The Copyright Term Extension Act of 1998 lengthened copyright terms, and no published works aged into the public domain again until 1 January 2019.

Since then, a new year of works has become free every January, which is why recent years have seen so many celebrated characters and books suddenly available for anyone to use.

Unrenewed and unmarked works

Many comics are free for a different reason. Most works published in the United States between 1923 and 1963 had to have their copyright renewed in their 28th year. Most were never renewed, so they fell into the public domain long ago. That includes a large share of the comic books of the 1940s and 1950s, whose publishers often did not bother.

Works published without a copyright notice before 1978 also entered the public domain, and works published before 1 March 1989 could lose protection the same way, unless they were registered within five years and the notice was added. Checking renewal and notice records is a key step before reusing an old comic.

Issues are not characters

The biggest trap is assuming that a free comic means a free character. Copyright protects specific works, so an old issue in the public domain can be reprinted, but later stories may have added traits, costumes or details that are still protected. Only the version of a character that appears in the public domain work is free.

Characters and titles can also be protected as trademarks, which do not expire as long as they are used in business. A publisher can still own the trademark on a character's name even after early stories have entered the public domain, so using a famous name on a cover can be riskier than reprinting the story inside.

Using public domain comics

For readers, public domain comics are a free library of the medium's history, from early newspaper strips to the comic books of the 1940s. Our short history of the comic strip is a guide to some of the best-known early work.

For creators, they are material: panels to study, characters to reinterpret, stories to answer. Anyone planning to use public domain characters in a new comic should keep a record of exactly which work they are drawing from, and be careful with names and logos. Our guide to making a comic covers the rest of the process.

A quick checklist

Before reusing an old comic in the United States, check four things. When was it first published, and is that more than 95 years ago? If it was published between 1923 and 1963, was the copyright renewed? Did it carry a copyright notice? And is any character or title in it protected as a trademark?

If the answers are clear, the work is yours to use, share and build on, just as the first creators of the medium built on everything that came before them.
