The facility is formally known as the Kenneth R. Penhale City of Helena Museum. Penhale is a Helena native and has served as President of the Shelby County Historical Society. He is the co-author of a 1998 pictorial book on the city's history.
You can see a number of other photos on their Facebook page, although that seems to have been dormant since 2015. In addition to the drag strip exhibit, the museum has lots of photos and memorabilia related to WWII veterans from the area and local mining and other businesses, and more.
