From what I can tell, this shape and decor has been attributed to Kralik. Shown are two sizes and two ground colors. The smaller (left) one measures 8" (20.3 cm) tall with a span of 6 3/4" (17.2 cm) - transparent cobalt windings on a transparent pink ground with light vertical texture. The larger one is 9 1/4" (23.7 cm) tall with an 8 3/4" (22.2 cm) span. It has the same application on a brownish ground. The smaller one only has a straight-line acid-stamped Czechoslovakia mark.
This decor can be found in a multitude of color combinations with various color threads on various colors of usually transparent or opaque "Tango" colors. It seems to be almost always on a single color ground.
Rather than make a collage of the images, I have posted links to a few similar items here on CW where, if you read the comments, a good deal more information will be found.
