I would still contact the USGA directly......and....R&A
Local Knoxville paper had prints of photos going back into the 30s at one time. Old prints in the files showed all the crop lines, etc. Newspapers are a likely source, and some have kept the photos. Have never inquired at the old, main line, big city newspapers
And some are selling old photos on eBay...ie...Tribune, Baltimore Sun...
I wouldn't doubt that those who have access could probably find something in the many online newspaper archives..
