This looks like a single collection of photos slides dating from the late 50s to late 70s. The subject matter of the slides runs the gamut. Most our landscapes, Panoramas or buildings. There are some individual and family photos. It appears like many of them are based in California, several could be from San Francisco neighborhoods. There's family road trips and vacation slides here also.

Most of the slides are Kodak Kodachrome, but there is also some GAF, Fotomat and AFGA. Some of the slides have writing, most do not. Most if not all seem to be very viewable. The slides are contained in Quick load slide trays of various types. There are TDC trays as well as Bell & Howell micro fit. There is also one tray which is empty which doesn't have a top. Please check the photos closely for complete details.
