Architecture Hall curator Bruce Gerrie has added to his already-impressive collection of relics, and the new permanent exhibit, titled "Elmslie and Sullivan", captures the swansong of the Chicago School of Architecture in its final terra cotta ornament. This exhibit showcases original architectural pieces from buildings of Louis Sullivan (considered the father of Modern Architecture) and his chief draftsman, George Grant Elmslie.

Also included in Gerrie's collection is cross that once adorned the Alexian Brothers' Hospital (also known as the original locale of The Exorcist) and the less-haunted collection of brass doorknobs, as well as numerous gargoyles—which can be seen throughout the museum—ornamental terra cotta from Chicago, and an impressive array of medallions.
