This is an old vintage vase attributed to ZBS designer Miroslav Klinger. It was probably made in the 1960s. It has an etched design that I think resembles tree bark. It is a common etched design on some Zelezny Brod Sklo vases. The light yellow color was named Citrine.
This vase has use scratches and minor chips on the bottom. There is a small flat flake chip 3/16" (3.4mm) wide at one corner of the base, 3 pinpoint nicks in the bottom of the base, half an inch from the flake chip, and one intact chip or bruise about the same size as the first, on another corner of the base. My last 2 photos show these. There are a few tiny white dots about 1/4 inch up from the bottom of the base, that I think are paint. I've scratched some off, but about 3 are embedded in the crevices of the design. I have not attempted to use a paint solvent on them, but you may if you wish.
