		<description>Growing up, if we were visiting my grandparents when the weather was bad the first thing I&apos;d grab was a stereoscope and its cards that one of my great-grandparents had as a child.  The images always seemed like mini-movies to me, since the 3d effect is so clear and so unexpected (hey, I was a kid, I had no idea how this sort of magic was done).  

A quick search online led me &lt;a href=&quot;http://www.rootsweb.com/~prsanjua/stereo001.htm&quot;&gt;this page&lt;/a&gt;, where I found several of the cards I&apos;ve got, some from &lt;a href=&quot;http://pics.amres.com/p_asp/a8998.asp&quot;&gt;this set&lt;/a&gt;, one from the &lt;a href=&quot;http://www.stereoviews.com/2957eht.jpg&quot;&gt;Civil War&lt;/a&gt; era (unfortunately I haven&apos;t pulled the cards out lately, so I&apos;m sure there&apos;s a lot that I&apos;m missing because I can&apos;t remember the captions well enough to search for them).  When my grandmother packed up her house to move, the set of cards and the viewer were the one thing I that I insisted on taking, since she was going to toss it out.</description>
