Here’s a new source challenge for you. Take your time finding material for this challenge. As you know, our challenges never have a closing date!
Alternatively, if you don’t have, or don’t want to use, a personal photograph, use public domain material. Here are some useful sites for historical family photographs:
Wikimedia Commons, category historical images of people; Library of Congress digital collection sets; Pond5 free historical public domain photos (will require some searching), and flickr’s The Commons (you’ll have to do some searching in this resource, too; here’s a direct link to historical family photographs on The Commons).
Finally, post your dreams, and, if you like, tell a story and share what the photograph means to you.
