This one doesn't have a caption as far as I know, but I'm making a command decision and identifying it as Mason Ross (1892-1908) and Daisy Barham-Ross (1890-1972) at Omaha Municipal Airport c.1950s. It's from my Grandmother's box of slides and I think this one was from Aunt Mary Ross-Gillespie's slides. The old municipal airport in Omaha was a red brick structure, so I'm fairly confident on the caption. Let me know if you think I messed up on it.
Mason and Daisy probably made the trip from Lake City, Iowa to Omaha to pick up or drop off Ward and Mary Gillespie flying to or from Arizona. I also noticed the family in the background of the photo, I think they may have just stepped into the frame during the photo. In the high-res scan you can read "CIPAL AIR P" above the door in the upper left corner.
