Today's image shows the Market Basket grocery store at Commonwealth and Nicholas Ave in Fullerton, around 1957. I had trouble identifying the location. Can you figure out why I had trouble finding Nicholas Ave in Fullerton? In any case, you can see that the big basket-weave sign is being painted.
I'm still confused about the big silver sphere in the background ( just above the green car's trunk). Is it a radar unit for a Nike Missile installation, (as I first guessed,) is it a fuel tank, (as Phil suggests,) or is it something else entirely? It doesn't appear in aerial photos of the area from 1955 or 1959. A very similar tank appears in the 1955 aerial, but it's probably half a mile farther away, near the railroad tracks.
While only featuring O.C. peripherally, anyone who grew up in 1960/70s Southern California can enjoy Wes Clark's "Avocado Memories" website. Mr. Clark thoroughly documents his childhood in suburbia, and takes us all along for a trip back through time.
I stumbled across an online tutorial on "Deciphering Old Handwriting" by Sabina Murray. Perhaps some of you will find this useful or at least interesting.
