Answer:

50- 100 years

70 years plus life of the author

Explanation:

Copyright is the exclusive right given to the creator of a creative work (such as literary, artistic, music, or education) to reproduce the work, usually for a limited time. It is used to protect the original expression of an idea in the form of a creative work, but not the idea itself. The public law duration of a copyright expires 50 to 100 years after the creator dies.

The lifespan of copyright for a particular work in the United States depends on several factors such as whether it has been published and the date of first publication if it has been published. Creative works created after January 1, 1978, copyright life span last for the life of the author plus an additional 70 years.

For an anonymous work, a pseudonymous work, or a work made for hire, the copyright life span is for 95 years from the date of first publication or a life span of 120 years from the date of its creation.
