WASHINGTON — How are your sleuthing skills?

If you think you're pretty sharp and have an interest in Civil War history, the Library of Congress may have a challenge for you.

The identities of many of the individuals who appear in ambrotypes and tintypes found in the exhibit, "The Last Full Measure: Civil War Photographs from the Liljenquist Family Collection," remains a mystery. Only a handful of images had any type of identification when the Liljenquist family acquired the photographs.

Some images of unknown figures do bear small clues, such as regimental markings and studio backdrops, which could help attach a name to the face.

The Library of Congress has established a Flickr page where visitors can take a stab at helping identify a select group of anonymous soldiers and civilians in the Liljenquist collection.
