Art Deco Czech Glass Vase Hand Painted Penguins 1930s

This is an art deco era vase that I believe was made in Czechoslovakia during the 1930s, although I cant be certain about maker or origin. If not Czech, it certainly was made by a quality glass maker. The vase is made of thick smokey topaz toned glass that is hand decorated with penguins. The penguins are quite wonderfully depicted, appearing quite animated and squawking at one another. They are rendered with what looks like stencilled white spray with orangey toned enamel painted beaks and white enamel painted eyes - the dark glass background provides context. The vase is trimmed with two gold deposit rings and the underside is hand polished. It measures 10 1/8 in height and has a diameter of about 7 at its widest. The glass has a wall thickness of 1/2 and the vase weighs 7 1/2 lbs. It is in excellent condition with no chips, cracks or wear except for a couple of light scratches on the underside due to surface contact, very minor (see last close-up photo). Wonderful quality vase for an art deco decor and/or for the penguin lover!
