The recent expansion to the Grand Valley State University art gallery will reopen to the public with an exhibition Saturday, Sept. 15 at 1 pm. The art gallery received a new second floor with the expansion and is dedicated to Mathias J. Alten work. Located on the downtown campus of GVSU, the gallery holds the most Alten works that are open to the public in the world. The second floor expansion was possible due to the generous support of George and Barbara Gordon. There are nearly 40 Alten pieces on the second floor, and on top of that there are 36 pieces on the first floor. Watercolors and oil paintings are on display, featuring Grand Rapids cityscapes and Dutch canal scenes, along with others.
