Thanks for all the responses. It's actually an bunch of photos I purchased as a bulk lot in Australia but so far I believe the photos belonged to 1 (or several) afro-american families from the USA. I did post a photo from a park t reddit and someone identified the park as Alamo Square in San Francisco. Another card mentioned fireworks at the coliseum which I believe is in Los Angeles so the limited info to date points to California. Am trying to get at least 1 name correct that I can work with but it's a challenge!
