Vintage studio pottery large Vase mid century modern overlap glaze earthtone mcm

Offering this amazing large vintage studio pottery vase with overlapping glazes that reminds me of Robert Maxwell pieces, it is signed on side near bottom but I can't make it out. It is also in very good condition with no chips, cracks, or scratches. Some tiny white specks on one area of side shown in photos that is probably from something painted rubbing against it and can probably come off. Quite substantial presence and weighs 6 pounds. Measures 13" tall by 7" wide.
