1/6 ambrotype in full case.. dates to around 1861, very early Civil War period. Inside of the case is writing: "Fred + Shubert" .. no last names. From a collection of 1850s and 1860s photos, one of which was marked with a Saint Louis, Missouri, photographer... so I believe it's likely that this image was also taken in or around there. Very good condition behind mat and glass. More info soon.. feel free to convo in the meantime. Boxed & insured PRIORITY MAIL. Next Day Air optional.
