Do you have a digital image of the old Ak-Sar-Ben racetrack?
I checked in our digital images collection and could not find anything. However, we have many photographs which have not been digitalized. To find out if we have this in our collection, you can either visit our Local History department, on the 3rd Floor of the W. Dale Clark Library at 215 S 15th Street or submit a Research Request. There may be a few associated with the research request.
If you have not already you may wish to contact some other organizations such as the Durham Museum which has a photo archive and the Douglas County Historical Society's photo collection
