Hung Liu: Control and Freedom is on view at Vicki Myhren Gallery at the University of Denver until March 24. Hung Liu was prolific and often returned to concepts, using new lenses and mediums, over several decades. Collage, oil painting, photography, lithography, tapestry, and found-object assemblage, among others, all make appearances. The subjects of Liu’s artworks are drawn from the artist’s collection of late nineteenth and early twentieth-century photographs, many being images of laborers, sex workers, refugees, and soldiers.
