Cobalt Blue Signed Monochrome Vase 8 1/2” Tall Vintage

Description

Monochrome Cobalt Blue Vase.
Do not know the country of origin or it’s age.
There are signature markings on the lip of the underside.
Would be able to see with a magnifier or enlarging the photos provided.
The inside is finished as beautifully as the outside.
The start of the round has a beautiful aura circling the Vase.
The vase - the circumference is 20” at this point and then tapers.
The height is 8 1/2 inches.
The base is 2 1/2 inches across.
The top lip is 3 inches across.
The piece is well balanced.
There is a vertical line across the base - I noticed that on one side where the vertical is - there is a ever so slight line of paint that would only be visible under intense light - on this side there is a tiny nick the size of a small pinky on the lower one forth of the piece - other side is more in line with the overall characteristics of the piece.
All in all a beautiful Monochrome piece.
Do not know the exact age or the country of origin.
There are white glare spots in the photos, this was difficult for me to eliminate, please disregard, there are no white spots on the Vase.
