body: Let's say it's 1910 and a photographer takes a photo but never publishes the original. Later someone else (with permission) uses that original photo to make a colorized postcard and publishes it. If the post card was published in, say, 1911, then it is public domain in the US, correct? But what about the original photo? Since the colorized version was published, is the original black-and-white version considered published as well? Or does it remain unpublished and therefore copyrighted for the usual creator's-lifetime-plus-70-years? 
  
  
  
title: Original unpublished, derivative work published, is original now considered published?
