\n

A stack of unidentified photographs is one of the most common obstacles in family history research. Nobody wrote a date on the back, and the faces are only half familiar. The good news is that photographs carry internal evidence: clothing, paper stock, printing marks, and pose conventions that pin a date to within a few years.<\/p>\n

This is the same logic archivists use. You do not need a lab \u2014 you need to look at four things in a fixed order. If you also have a known birth date for a person in the photo, you can estimate their age in the image<\/a> and cross-check it against the date the visual clues suggest.<\/p>\n

Step 1: Identify the Photographic Process<\/h2>\n

Step 2: Read the Paper and Printing Marks<\/h2>\n

Turn the photo over. A divided-back postcard (a vertical line splitting the back) dates the print to 1907 or later. Studio imprints give a city and often a street address; directories let you date the studio’s tenancy. Embossed borders peaked in the 1890s, while scalloped edges were common in the 1940s and 1950s.<\/p>\n

Step 3: Date the Clothing and Hair<\/h2>\n

Fashion moves fast enough to bracket a decade:<\/p>\n
