In a previous entry, I mentioned the book Lincoln in 3-D and how I enjoyed viewing those pictures like that.
Well, the Civil War Preservation Trust's website has a few more 3-D pictures as well, with cooperation from the Center for Civil War Photography(CCWP). Some of them are in the book I mentioned, but for those who do not have the book, but have a good pair of 3-D glasses, it is worth the time to check these views out.
If you don't have such a pair of glasses, you can also order a pair free from CWPT. (I have ordered some, but the set I had in the book works for this site as well.
