How can I find out if a picture has a copywright?

Question

I found a picture on craigslist and it doesn't have anything on it as far as a trademark or copywrite so I want to print it on a t-shirt and wear it. How can I find out if it has a copywrite?

Answer 1

All photos have a copyright to some degree (if not under employment, it stays with the photographer, if employed it goes to the company). Only very old ones might end up in the public domain. Is it possible to post the picture here?

Answer 2

Contact the artist or the publisher of the artwork. Ask them if it's copyrighted. If it is, then ask for the copyright number.
