I need to reproduce three images from the following sources (all from the mid-1950s) for an upcoming publication:
1. Times of India online database via ProQuest (advertisement)
2. Guangming ribao online database (photograph)
3. Archived personal papers (Newspaper photograph that I personally clicked at the archive)
Do people know how copyright works in each of these cases? I am trying to track down reproduction rules in each case and any advice or information would be much appreciated.
