Popeye, Tintin in public domain from 2025... but minus spinach & red hair

Popeye and Tintin's early versions enter the US public domain in 2025, allowing their use without copyright restrictions. However, later additions like Popeye's spinach and Tintin's signature colors remain protected. Literary classics by Faulkner, Hemingway, and Steinbeck also join the public domain.
