New York-based artist and printmaker Lothar Osterburg presents a mysterious and magical world of fanciful bridges, shantytowns, and flying machines -- all actually small models he has built from found materials, which he then prints using the traditional photogravure process, bringing each scene to life with a range of subtle greys and rich dark tones. Opening reception; show runs through March 17; gallery hours Mon.-Fri., 10 a.m.-5 p.m. Highpoint Center for Printmaking, 2638 Lyndale Ave. S., Minneapolis. 612/871-1326, www.highpointprintmaking.org
