Frank Hardy Made My Photographs Two

This is a photograph someone brought to me twenty years or so ago for a copy job.  Usually I never bothered to save these copy jobs, but this was one that I thought was really interesting, so I made me a copy negative and put it away.  I do not know the year and I cannot remember anything about the person that brought it in.  I do not think that I have ever seen a photo that contains so many bi-planes in one image before.  I posted this on the old site and I did not get one comment from anyone, which amazed me since I thought someone would run across it and know something about this image.  You know that it had to have been made after 1937 because that was the year that the Golden Gate Bridge was completed … I believe.  You also see that there is hardly anything built were San Francisco is today.  Pam and I flew out to San Francisco back in 2000 and it was one of the most enjoyable trips that we have and we have been on a few.  On my personal blog http://frankhardyphotoblog.com/ , I have posted some b&w images that I made on that trip.  Thanks for looking …
