This is a picture of General Abner Doubleday, U.S.A. This picture is available on Commons. It is available from the Library of Congress (LC-BH82- 150 B). This picture was cropped in order to be able to upload it onto the Wikimedia servers; its current size is 7,87 MB.
The date of this picture is between 1855 and 1865, at the time it was popular to create what are stereoscopic pictures so these are the two pictures needed to create this effect. Durova is doing great work by restoring pictures.This is a partially restored picture and it is very much improved. In a way, this work is similar to the work done in Wikisource. Important old pictures are restored and by their inclusion in Commons they are available in all WMF projects and under a Free license when downloaded for other uses.
There are many other pictures that are really relevant, the SF earthquake, the Warsaw ghetto uprising or Douglas MacArthur landing at Leyte..
I find it awesome that Commons is evolving and doing these great things that we do not hear much about. What else is happening at Commons that we do not know about ??
