~1864-1870 CDV PHOTO YOUNG WOMAN - CIVIL WAR/POST CW ERA.  CDV in good condition, just some typical age spots & a little bit of age lightening - see pix.  Exact year taken a bit difficult because some conflicting issues with both the subject/contents of portrait, as well as the photo itself and way it's taken.  Some say clearly 1864, others 1870, and with no photographer info, so can't use that to narrow it a bit further.  But still have it down to about 6-8 years in 1800's, and during a critical era! :)  Also note there is a hint of added color to collar bow (potentially another age question!) - see pix - but very light.
