Dick Eastman in his Online Genealogy Newsletter (blog) points out that Family Tree Magazine is giving away a free e-book to those who sign up for the magazine's free, weekly e-mail newsletter. The book is the 42-page Best of the Photo Detective, a step-by-step guide that helps you examine old family photos for hidden clues to when they were taken and who’s in them. It includes an exclusive excerpt from Uncovering Your Ancestry Through Family Photographs by the Photo Detective, Maureen A. Taylor.
Dick suggests signing up at http://www.familytreemagazine.com/enews. After you submit your registration, you’ll get a link to download the book as a PDF file. You can then view it on your computer's screen or print it on your local printer.
