Here is the pic of the bottom of the pitcher (they both look alike on bottom)
I was blown away that someone described the pitcher with a scale pattern, you were spot on. I never would have thought about that part, I was too focused on the color, design, material, etc...great work and thank you
I also like the theory on the guitar. I can't find the diamond pattern on old Dobro's, possibly because it's a "knock off". I'll admit I wondered that at one point in time when I read Dobro lost their patent but didn't follow it up, guess I should have. My grandpa always told me to make sure I loosened the strings after playing to prevent it from warping so I assume it's early and without the support rod.
