Determining the location of the particular stand shown in our photo proved to be a bit of a challenge, until I came across the Giant Oranges page on the RoadsideArchitecture.com website. There I found a scan of a real-photo postcard (click here to see it) showing the same Orange Inn vintage orange juice stand under an old oak tree. The good news is that after I enhanced the postcard image a bit, the writing at the bottom became distinguishable, and reads:"Everything in Orange. Foothill Blvd, Pasadena, Calif." Foothill Blvd was part of Route 66.
Homestead Museum in the City of Industry. And they even listed the Orange Inn's former address: 2458 Foothill Blvd.
Now comes the sad part: I looked the address up on Google Maps' Streetview feature and compared the ridgeline in the backgrounds of the above photo and the post card, and got this approximate view of the site:
Well, at least you can probably still get orange juice at that Mobil station....
While the Orange Inn is long gone, a few other orange stands still stand today! Including one in Florida!
