I have a couple of those Spreckels Sahara Sugar cubes and I never knew where the factory was located either.
I also have a grouping of that style of Sahara swizzle sticks, but mine are different colors. My inventory sheet says I have 18 different colors
but all I can find at the moment is 17. I am sure you have all these as I know you have an extensive Sahara Collection.
The other item pictured is a Sahara bar of soap that I had not seen before.
