Vintage Native American high quality Blackware Pottery Vase, Signed E. Martinez, Rare Recessed Design, Puebloan

Unique recessed design on a classic black on a black pottery bud vase. Gloss and matte finish combine to create a unique artful design high quality in recessed area at vase's front panel. My online research yielded no other similar designs. Stands 10.5” tall. No chips or cracks. There is a small spot at the bottom of the recessed panel that may be a manufacturing goof. See last photo.
