This thread brings up things I've always wondered about,and thank you Miguel for responding.
Now,here's where I get confused(and I appologize if I'm taking this thread off-track)
If everything that was published in the U.S before 1923 is public domain,does that mean,for instance,you could take a scan of,say,Mordecai Brown-from 1909-1915,and print it onto T-shirts and sell them-is that legal?
