Blue Graniteware Cup Circa 100 Years Old Plus

Another graniteware cup similar to the one I posted a few weeks ago. Another cup that was around in the cowboy era although the cowboy era was winding down at that point. Graniteware started appearing in 1885 when railroads were making cattledrives shorter and barbed wire cutting off the range.
In the meantime it is a very nice blue color with a bit of white swirl. Note quite sure what to call the blue color, Aqua or Robins egg blue perhaps. It is a good color regardless.
Also in the meantime I have been washing and cleaning items on top of cabinets and other dusty areas. A rather large project that should be finished in 3-5 years.
