Our latest exhibit we wanted to include as many building by Architect Wallace Dow but didn't have enough room. We decided to make a flip panel interactive to include 72 of his over 120 buildings. It's construction is a threaded rod, double bolted to hold each piece in place but allowing them to spin. The graphics are laminated with an adhesive back. You can see this at the Pettigrew Home and Museum in Sioux Falls.
Museum, The National Underground Railroad Freedom Center. I loved teaching my children about one of America's darkest times in history and even events of today. It opened their eyes and they learned so much!
