At the end of the center hall and just past the elevator is the Alpha Delta Kappa Heritage Room. In 1971, the mail room was remodeled to provide a museum which would preserve and display the archives and other materials significant to the history of Alpha Delta Kappa. Dark wood paneling and vanilla carpeting offer a neutral background for the archives and artifacts. The room was designed with concealed storage and display shelves for archives books and built-in display cases.

The cases are lined with monk's cloth which Agnes used as a cover for the initiation table when she traveled the country installing the first chapters. The cornucopia she used is also on display along with early record books maintained by Marie. The crest hangs over bookcases at one end of the room. On these shelves are books authored by Alpha Delta Kappa members. The glass cubicles down the center of the room display favors from all the National and International conventions. These cubicles were given in honor of Helen W. Clifft by her husband. The large glass-shelved display case holds many items of historical significance as well as gifts. All items are described in tag copy located near each display. The International Presidents' Book, the Woman of Distinction Book and the Omega Book are displayed on the counter nearest the door.

Center Hall

The curio cabinet in the center hall was purchased with contributions received following Marie Neal's death. Many items on display in this cabinet were gifts given her through the years.

Art work throughout the first floor work areas and hallway include framed posters and prints by internationally acclaimed French artist Michel Delacroix, the official artist of the 1996 Centennial Olympic Games in Atlanta and the 1995 Special Olympic World Games. Before establishing his art career, he taught art in Parisenne public elementary schools, supporting a family of five.

Referred to as a master of the 'naif' or naive style of painting, he uses his childhood memories as the subjects of his distinctive style. Inspired by his love for children and a serious childhood illness, he established the Michael Delacroix Foundation a non-profit organization founded to bring happiness through art to children throughout the world who are confined by temporary or permanent illnesses.
