Family Tree Magazine is giving away a free e-book to those who sign up for their free, weekly E-mail Update newsletter.
The book is their 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 Maureen A. Taylor. Maureen really knows her stuff as deals with family photos. I’ve read her materials over the years, and can say that they are always useful.
Family Tree Magazine’s E-mail Update newsletter delivers the latest news, tips and resources for doing family history research. You can sign 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.
Be careful. When I went to sign up for the free newsletter, I first had to close a form for Family Tree Magazine that overlaid the form for the free newsletter. I just had to click on the x in the upper right-hand corner of the box. Not that I have anything at all against Family Tree Magazine, but I do not need two subscriptions to the publication!
