Civil War display

At the St. George Tabernacle, there was a display of Civil War memorabilia that I wanted to see.  It was on display for the 4th of July so we decided to go see it.  They had flags from all different times in the history of the US.  They had the cuffs that Lincoln was wearing when he was killed.  They had the history of the flag on display also.  Then they had this...

 I had NO IDEA that Darth Vader and Superman were in the Civil War!  That wasn't something my teachers ever taught me in history class. ;)  I don't know why those were part of the display but they were the original ones used in the movies so that was cool to see.
