==History== 
 The article currently claims that "The building... was intended to be a more permanent structure than the other Exposition buildings...".  We just toured this museum the other day, and the museum itself has a history exhibit (on the lower level, near the food court) that claims that this building was also designed to be 'temporary', but sometime was converted to 'permanant' by replacing the exterior (formerly plaster) with limestone, and remodeling the interior over the years.  They even had a picture of the museum looking delapated before this exterior conversion existed.  I don't have a cite other than this, so I won't change the article quite yet.  But I do believe the current info in the article may be incorrect...
