I have started a new Flickr page called "Civil war Veterans buried in Missouri and Missouri Civil war Veterans buried Elsewhere". You can find it's photographs at:
http://www.flickr.com/groups/1168354@N25/
Flickr (Yahoo photos) has free accounts which have a limit of about 100 photos but I look forward to more people joining this group and uploading photos to the group. If you look at the page it has Civil war Veteran tombstone pictures but like my "Civil war Veterans buried in Kansas" group it can be tombstone photos, old photos of the Civil war Veterans or documents about Civil war Veterans buried in Missouri or Missouri Civil war Veterans buried elsewhere (of course obeying copyright rules).
