Stereo Optic Cards Philippine American War and similar items

Lot of stereo viewing cards by Underwood, mostly photos of the Philippine American War, with a couple from the Spanish American war, and a few with American themes. These have been in my family for generations. I remember looking at these as a child, and being fascinated with the 3D effect and learning bits of history. One card is hand colorized. One features the Merrimac! Time to downsize, and the kids aren't interested.
