These photos are available thanks to the Strahorn Library and Museum Volunteer Joe Stupar's time spent scanning them.

Due to concerns expressed by some about rampant piracy of photos on the internet, restrictions have been placed on posting photos from the Museum's collection here. The requirements set forth state that they must be low res and watermarked. We apologize to the vast majority of our patrons who only use this site as intended, for personal enjoyment and information gathering.
