The Mary Engelbreit Christmas Experience in the St. Louis Children’s Illustrated Art Museum at Crestwood Court’s ArtSpace now is open. The exhibit features a walk-through experience of the children’s holiday classic ”Twas the Night Before Christmas’ by Clement Clarke Moore, illustrated by St. Louis native and internationally known artist Mary Engelbreit. Museum visitors on Dec. 1 were able to meet the artist during a special event. The free exhibit is open to the public, although donations to support the nonprofit museum are welcomed.
